New Shape to An Old Medical Patent

John Rizvi — Fri, 17 Jun 2011 09:24:22 -0500

For decades heart surgeons have used stents to prop open veins and arteries after angioplasty surgery. Now, a new medical patent aims to help keep the “flow” open in other areas of the body as well.

Allium Medical Solutions Ltd. – developer and manufacture of site-specific stents – has just been granted a patent by the Japanese Patent Office for stents used to treat enlarged prostates.

Allium makes an entire line of stents for use in various places along the urethra. But what makes this one different than their other stents (and ones heart surgeons use) is that instead of a balloon-like stent, this one is shaped like a triangle.

Why Patent a Different Shape?

The prostatic urethral lumen (the part that gets “squeezed” when the prostate is enlarged) has a unique size and shape in each man. Sometimes it’s longer. Sometimes it’s shorter. And each prostate has different contours. Because of this, traditional stents that are cylindrically shaped don’t always do a great job of keeping the flow open.

This new patented medical device takes aim at that problem.

The triangular shape of the stent allows it to fit unique male anatomy better, resulting in higher flow volume and improved comfort compared to existing stents.

It’s called the Triangular Prostatic Stent.

Also – and this is what makes it really unique – it doesn’t put the guy’s voluntary continence mechanism at risk. In plain English, guys can control when they go to the bathroom.

What is a Patent Like this Worth?

Let’s take a look at the numbers…

Prostate cancer develops primarily in men over 50 years old, with more than 80% of men developing prostate cancer before their 80^th birthday.

It is the most common type of cancer in men in the United States, with 186,000 new cases in 2008 and 28,600 deaths. It’s the second leading cause of cancer death in men in the U.S. and UK behind lung cancer. And the problem is growing.

And since traditional prostate disease treatments focus on removing the cancer (either through chemotherapy, radiation or surgery), side effects include incontinence and impotence.

Surely, an alternative that reduces these risks would be a welcome option to any patient.

For their efforts, Allium won the 2011 Medical Design Excellence Award competition for the Triangular Prostatic Stent. This competition recognizes the achievements of medical product manufacturers and new medical patents that are changing the face of healthcare.

The One Letter Medical Patent Mistake

John Rizvi — Mon, 09 May 2011 10:04:10 -0500

Patents give you 20 years of exclusive ownership of your idea.

That means no one else can sell your idea...no one else can manufacture your idea...no one else can import your idea. And if they do, you can sue the pants off of them (sometimes getting as much as 3 times the damages from them as well as reimbursement of your attorney fees).

But that's only if the patent application is properly prepared.

Said another way, if you make a mistake on your application – even a tiny one – you can flush those twenty years of protection down the drain.

How small of a mistake can put your idea at risk?

Very small. 99.99% of your patent application can be squeaky clean: no errors, no omissions, nothing wrong. However, just that .01%...sometimes just ONE letter...and you are out of luck.

And that's exactly what happened that cost one company potential millions of dollars.

The One Letter Patent Snafu

A few years back, Central Admixture Pharmacy Services (CAFC) sued Advanced Cardiac Solutions for patent infringement relating to a chemical solution used during heart surgery.

A certificate of correction was sought on the patent and was issued by the patent office to replace all instances of the word "osmolarity" with the word "osmolality".

You might be thinking what's the big deal? So they changed the "R" in osmolaRity with a "L" so that it reads osmolaLity. The problem was changing the two words broadened the claims of the patent.

Enough so that even though the district court found the certificate of correction proper, the CAFC disagreed, resulting in massive litigation.

Seeing as average legal costs for patent litigation can easily run over a million dollars through trial, it pays to make sure a patent is written correctly the first time.

With that in mind, let's explore a few common patent application mistakes.

3 Huge Patent Application Mistakes

Patent Application Mistake #1: Not filling out the patent application in its entirety

Believe it or not, patent examiners reject applications simply because they do not contain all the necessary ingredients. If you fail to include required elements, such as a background section or discussion limitations of the prior art, or setting forth scope of the invention in claims...your patent application may be dismissed immediately.

Patent Application Mistake #2: Being too specific

Patents are title to property. And explaining too many aspects of your invention in excruciating detail can actually shrink your intellectual property...and...reduce the profitability in the long run.

For example, imagine you have a new invention that uses a metal spring.

While you are describing your invention in the claims of the patent, you explicitly state it uses a metal spring. Now, what's stopping another inventor from copying your invention piece for piece, but instead of using a metal spring they use a plastic spring, rubber spring or even an elastic band?

Do you see how this seemingly small specific wording could invite other people to copy your idea and make small changes that would invalidate your patent?

Patent Application Mistake #3: Being too vague

Now this may sound contradictory to mistake #2, but too many patent applications do not go into detail about how their idea works. Do not assume your idea is understood. Failing to describe the idea in detail could leave "gaps" in the patent, leaving it vulnerable to being found invalid. If your patent is invalidated, others can come in sell similar products with no liability.

Make no mistake, applying for a patent is tricky.

Worst of all, you may not know you even made a mistake on your patent until YEARS after submitting the application...when an examiner at the patent office finally gets around to reviewing your patent application. Sometimes the mistakes are not caught until you are ready to enforce the patent against a competitor.

Biggest Medical Device Trends of the Next 10 Years - Part Three

John Rizvi — Thu, 20 Jan 2011 14:07:35 -0500

This last article wraps up our discussion of medical device trends.

In part one of this article, we talked about obesity and heart disease…two growing trends in America that will require new and innovative medical devices. You can read this article here.

In part two of this article, you learned about the growing threat of diabetes and how antibiotics can't keeping up with the evolution of bacteria…and what opportunities these two trends present to inventors. More on that here – link.

Today, we will look at one of the scariest and multi-faceted diseases today and the how to ease the blight of our aging population.

Medical Device Patents and Cancer

Cancer is responsible for roughly 562,875 deaths per year, making it the second leading cause of death in the U.S.

What's worse, the World Health Organization (WHO) predicts cancer rates could increase 50% by 2020. The reasons? Too much smoking, poor diets and infection.

Top 10 Cancers According to the CDC

The WHO suggests three ways to curb cancer related deaths.

"Action now can prevent one third of cancers, cure another third, and provide good, palliative care to the remaining third who need it, "said Dr. Paul Kleihues, Director of the International Agency for Research on Cancer (IARC) and co-editor of the World Cancer Report."

For inventors of medical devices, the third piece of advice "good, palliative care" could be a goldmine.

Obviously, there could be advances in chemotherapy. And any other sort of drug that treats cancer would be welcomed with open arms. There are varied forms of radiation therapy used. And cryosurgery…or using extreme cold to treat tumors sounds like an area ripe for improvements.

But those are after the fact.

There are opportunities for inventors to improve early detection methods. Specifically screenings. For example, advances in screenings for cervical and breast cancers have increased the odds for prevention and successful cure.

And the list goes on.

Medical Device Patents and Elder Care

Since 1960 the average American lifespan has increased by 8.6 years (to 78.4 years up from 69.8). With this growing elder population comes a greater tax on the nation's nursing homes or at home care options.

The latest census data (from 2007) shows 7.4% of Americans aged 75 and older lived in nursing homes in 2006, compared with 8.1% in 2000 and 10.2% in 1990. While the data are trending down, I'd bet that the global economic meltdown in 2008 has dramatically reversed this trend.

To make matter worse, most people who enter nursing homes can't even afford to be there. According to a 2007 USA Today article:

"The average nursing home patient runs out of money within six months and must go on Medicaid, Markwood says. That, she adds, "will not only bankrupt individuals but also the Medicaid system."

All these statistics add up to a sobering reality. The number of people in nursing homes is only going to grow and it will cost more money to keep them there.

So, where are the opportunities for inventors? I see two areas.

First, new patents for medical devices for people who opt for in-home care. At the core of these inventions will have to be making life easier for the caregivers. Think walk in tubs instead of tubs you have to step over. Or handrails for bathroom facilities.

Second, new patents for medical devices for nursing homes. These will have to focus on reducing operating costs for the homes. Maybe less expensive lift devices.

These medical trends are not going anywhere and could be an on-going goldmine for any smart inventor.

Biggest Medical Device Trends of the Next 10 Years - Part Two

John Rizvi — Mon, 17 Jan 2011 13:46:07 -0500

In part one of this article, we talked about obesity and heart disease…two growing trends in America that will require new and innovative medical devices. You can read this article here Medical Device Trends Part One.

Today, we will look two more large-scale health issues that will require new technology, innovation and patents.

Medical Device Patents and Diabetes

Coming in as the seventh deadly killer in the U.S., Diabetes claims roughly 71,382 lives per year. 17.9 million Americans live with diabetes. And another 2.5% of the population does not know they have the disease.

In fact, since 1988 there has been an across the board increase of instances of diabetes regardless of age, sex or ethnicity.

Diabetes is up in Every Category (Click for larger view)

Diabetes leads to greater incidences of heart disease and stroke, high blood pressure, blindness, kidney disease, neuropathy (disease of the nervous system) and even amputations.

And diabetes is a $175 billion per year (and growing) industry.

Surely, creative new patents and medical devices will need to be invented to fight this dreaded disease. What are some of the opportunities for inventors?

There are two types of diabetes. People are either born with type-1 diabetes, or they develop type-2 diabetes. Both versions result in the pancreas producing little or no insulin (a hormone needed to allow sugar to enter cells to produce energy).

Traditionally, diabetics are treated with insulin injections to supplement the lower amounts in the bloodstream. Perhaps there is some invention-in-waiting that is less painful/intrusive than injections? Or maybe you could invent an "insulin pill" that slowly releases insulin over the day? An insulin patch?

Medical Device Patents and Antibiotics

Nearly 100,000 people a year die from antibiotic resistant infections in the United States alone. And doctors are fearing it's only going to become more common.

The reason? Antibiotics are losing their potency.

Here’s why, human beings are a vastly complex creature. We have multiple systems for pumping blood, breathing air and sending electrical systems back and forth. Bacteria are so primitive they don’t even have a nucleus.

Our complexity betrays us. The simple antibiotics we’ve used for the last half century have prompted bacteria to evolve. To develop biological countermeasures that are rendering antibiotics harmless. This wouldn’t be a problem if we were still discovering new antibiotics. But the vast majority of antibiotics were developed over twenty years ago.

What can inventors do?

Inventing new antibiotics is NOT the answer.

I think the more lucrative area for inventors is preventing bacterial infection in the first place (if you’ve seen the explosion in antibacterial products over the last twenty years, then you know what I’m talking about).

More and more people will be scared by news accounts of these new “super-bugs” and will look for different ways to protect themselves.

That’s it for part two of this article. In part three we will look at the growing threat of cancer, and where the most help is needed…and…why you might want to consider how to help seniors live out their golden years.

Biggest Medical Device Trends of the Next 10 Years - Part 1

John Rizvi — Fri, 07 Jan 2011 11:31:00 -0500

Fifteen years practicing patent law, and I’ve seen hundreds of medical device ideas and patents pass through my office.

The nice thing about seeing all of these innovations in the early stages of development is watching how they grow and make a huge impact in the industry. How they ride trends and break ground on new ones.

Seeing as how this is a New Year and a New Decade, I thought I’d take a crack at guessing what the next biggest trends in medical device technology will be over the next few years.

I started by spending a few hours researching the hard numbers on some of the biggest health problems affecting American’s today. Then I took a stab at what I think is to come. Hopefully this will shed a little light to where new inventions will have the biggest impact (and where inventors will find the biggest opportunities).

Keep in mind these are just my best guesses. I may hit the nail on the head or my crystal ball may turn out to be a little fuzzy. Let’s begin with one of the biggest epidemics of the past fifty years.

Medical Device Patents and Obesity

According to CBS News, Americans spend about $35 billion a year on weight loss products.

And that number is sure to grow. The following chart shows the rate of increase of overweight and obese Americans since 1960. If you look closely you'll see that obesity has risen from about 12% of the population in 1960 to over 30% today!

Meanwhile, overweight individuals have hovered at about 30%.

What this means is that more and more people will be looking for creative solutions to lose weight.

So, where are the opportunities for inventors?

Obviously, products that help people lose weight. There are thousands of patents for different exercise machines and the market is littered with trademarked diet schemes and marketing approaches.

Also, I believe there will be more products that promise to keep the weight off in the first place. For example, at my local grocery store they sell a version of an avocado called a "slim-cado". It has about half the fat of a regular avocado. I'm not sure how they did this, but it sounds like a candidate for a patentable procedure.

And of course there are the drastic procedures like gastric-bypass which uses specialty medical device patented tools that could be improved.

And the market for medical device patents doesn't stop here. The growing obesity epidemic will create an even greater need for patents in other areas of medicine.

Medical Device Patents and Heart Disease

Heart disease accounts for roughly 616,067 per year, giving it the dubious distinction of being the leading cause of death in the U.S. The surprising thing about this number is that it is just a fraction of how many lives were predicted to be lost to heart disease.

Why is this?

Maybe it’s greater awareness of the hazards of smoking. Dietary changes. Or more exercise.

I think it’s because of greater funding for treatments and cures. A quick web search will return thousands of charities and donations that host venues to raise money for heart disease.

With that in mind, I believe research and development into medical devices to treat heart disease should be big business for years to come. And then of course there are the patents on the inventions and improvements to surgery devices (think stents for coronary artery blockage).

And don’t forget about post-surgery needs. The average hospital stay after heart surgery is 5-7 days. During this time there are all sorts of tubes, wires and diagnostic equipment involved, all of which can be improved (which I’m sure some smart inventor is working on right now).

In part two of this article we’ll see where the next wave of new medical devices will come from by exploring one of the fastest growing health problems in America…and…the commonly over-abused drug that is quickly losing effectiveness (and is in dire need or replacement).

The Biggest Medical Patent Opportunities for the next 100 years?

John Rizvi — Mon, 13 Dec 2010 16:07:25 -0500

A few years back a friend of mine had surgery on his knee to repair a torn ACL (the main ligament in the knee). They put him under. Two hours later when he woke up there were three tiny incisions – no more than half an inch long.

Today, you can't even see the scars.

Twenty years ago surgeons would run a scalpel from the top of your thigh halfway down your shin. And this scar would be visible from across the room.

The evolution of medical devices over the last twenty years is astonishing. But the biggest medical patent opportunities for the next 100 years won't be developments in better tools for surgeons. They'll be tools that begin to replace surgeons altogether.

The Flood of Medical Patents for Robots

Half of all prostate cancer operations in the U.S. are performed by the da Vinci surgical robot. It stands nearly 5 feet tall and has four mechanical "arms" with cameras and interchangeable tools to cut, pinch and snip cancer into oblivion.

Patented Prostate Removal Robot

Over 1,000 of these robots are in operation around the world, at a price tag of one million bucks each (that's over a billion dollars worth of robots for prostate cancer alone!)

The robot is controlled by a surgeon who sits in a nearby room in what looks like a video game control cockpit. In this cockpit the surgeon watches several screens and controls the mechanical arms with perfect precision.

Because this approach to prostate surgery spares delicate nerves, this is a cancer cure that doesn't leave men impotent and incontinent.

Tools for the DaVinci Robot

This is a far cry from prostate surgery years ago when surgeons couldn't even see the prostate and had to rely on feel alone to remove the cancerous gland.

A Growing Trend for Medical Devices

Robots are not just confined to operating on prostate cancer. Hearts, throats, joints, spines and brains are being mended with the help of these new addition of medical devices. And it doesn't look to stop anytime soon.

Cardiac surgeons are using robots to perform bypass surgery without using rib spreaders
Robots make it possible to extract a cancerous thyroid gland through the patients armpit, instead of through the throat which leaves a nasty scar
Some throat surgeries used to require large incisions, pulled teeth and broken jaws...now robots enter and exit through the mouth

Who knows...in a few years my friends tiny incisions to replace his ACL may seem barbaric. A Florida company, Mako Surgical, holds a patent on a robotic arm to assist in surgery on arthritic knees.

Top 5 Medical Patents from TIME's 50 Best Inventions of the Year

John Rizvi — Sat, 04 Dec 2010 15:34:24 -0500

The November 22 issue of TIME magazine contained an article any future patent holder would love. The 50 Best Inventions of the Year showcased everything from flying cars to mosquito killing lasers. Here are the best medical patents from the Time Top 50.

Medical Patent #5: Used Cars for Babies

Premature babies have a new ally...junkyards. The NeoNurture incubator utilized old car parts to make functioning incubators for newborns. Headlights for heat, a dashboard fan blows air, and it can even be powered by a motorcycle battery. Finally, something useful for a Yugo.

Medical Patent #4: Life

Putting shame to the billions of years it took life to emerge on planet Earth, J. Craig Venter has managed to create life in just 15 years. Using simple off-the-shelf chemicals, Venter managed to reconstruct the genome of a bacterium that divides and replicates just like any other bug. Gloom and doom science fiction writers, sharpen your pencils.

Medical Patent #3: Great News for Smokers

Mixing blood vessels, collagen, stem cells, nutrients and a little science, researchers have created the lifelike tissue that exchanges oxygen and carbon dioxide just like normal lung tissue. Starting with a skeletal rat-lung, the lab grown lungs are powerful to assume 95% of a normal lung's inhaling and exhaling functions. Smokers around the world are encouraged not to hold their breath waiting on human implants.

Medical Patent #2: Replacement for the Wheelchair?

The makers of eLegs exoskeleton have designed an exoskeleton that may help paraplegics to walk again. The exoskeleton is composed of robotic prosthetic legs that use artificial intelligence to mimic a natural human gait. The wearer controls the machine using two crutches. Could this be the first step in a real Iron Man suit?

Medical Patent #1: Made to Order Organs

Imagine if you could print yourself a brand new heart as easily as you could a weekly status report. That's exactly what San Diego based companies Invetech and Organovo plan will happen with the 3-D Bioprinter. Based off of decades old dot-matrix printer technology, the printer has two printheads – one sprays out a gel that forms the shape of the desired organ...the other fills it in with living cells. Imagine a new liver custom made for you in a week. Alcoholics rejoice!

When Simple Is Better...A "Medical Device" that Prevents a Certain Type of Asthma?

John Rizvi — Wed, 01 Dec 2010 12:18:39 -0500

If you think you need to patent a wildly complex invention to make boat loads of money in the "medical" field, think again. Sometimes simple is better.

Take for example a story I came across while thumbing through the recent issue of Popular Mechanics.

A Medical Device for Prevention

The Popular Mechanics article says...

"Tile-setter Joel Beaton spent 17 years inhaling dust from powdered grout and mortar, which often leads to "potter's rot," or silicosis, an occupational lung disease marked by asthmatic symptoms. Now Beaton has invented (and patented) an attachment that snaps onto a mixing bucket and keeps dust from escaping. The tool evenly distributes the vacuum's suction so it draws in the maximum amount of debris. It's a simple idea, with brilliant results."

After reading the article I visited Beaton's website, www.waletale.net, and found two pictures that beautifully illustrate how this simple "medical device" sucks grout and mortar dust out of the air, preventing lung problems for tile setters.

Before and After Wale Tale

Three Rules to Keep in Mind for a Simple Medical Device

If you're not a Nobel Prize level doctor or have a Phd in biology, anatomy, or an area of medical science – but still want to profit in the world of medical device patents – here are three things to keep in mind.

Medical Device Patent Rule #1: Common Situations that Lead to Health Problem

Many new patents grew from a need to protect workers who are exposed to health risks on a recurring basis.

A few common examples are:

Gloves for lawn and garden workers so they don't cut their hands
Helmets for construction workers so they don't get knocked out by falling debris
Surgical masks for doctors and nurses so they don't breath in germs
And on and on...

Joel Beaton identified a frequent situation that caused a long term health problem. Look around the type of work you do day in and day out an ask yourself: Who is exposed to constant health risks?

Medical Device Patent Rule #2: Simple Solution

After you've identified the problem, here are a few questions you can ask yourself that will help you come up with a simple solution.

Is there something that already exists – that you can tweak a little bit – to fix the problem? In Beaton's case, he designed a simple attachment for a common worksite tool, the shop vac. Can I make it simple so anyone can use it?

Medical Device Patent Rule #3: Cheap to Produce

If this is your first attempt at patenting an invention, you probably don't want to bet the bank on it. So design something with as few moving parts as possible (and preferably out of a cheap material like plastic). That way if you get the patent, it will be much less expensive to manufacture and sell.

Worst Medical Patent of the Century?

John Rizvi — Mon, 22 Nov 2010 16:03:20 -0500

Most medical patents help you get healthier and as a medical device patent attorney, I take a special interest in news and commentary relating to medical and dental patents. I came across this one medical patent, however, that allegedly killed thousands of people, many of them women and children.

Imagine the following scenario...

You step onto a harmless looking machine. On top of the machine are three viewing ports. One for you. One for your mother. And one for the clueless machine operator. With the push of a button, all three of you are exposed to 20 to 45 seconds of radiation.

To put that into perspective, today's x-rays only last long enough to take a picture...usually less than a second.

The result? Birth defects, tumors, cancer and death.

Does that sound like a horrible Nazi experiment? Well it's not. It's actually occurred in thousands of shoe stores across the United States did from the 1930's to 1950's. You read that right...shoe stores.

Dangerous Use of a Worthwhile Medical Patent

The medical device is called a shoe fitting fluoroscope. It used radiation to produce an x-ray of the foot inside a shoe (to help in fitting). The three viewing ports on the top of the cabinet would allow you to see a fluorescent image of the bones of the feet and the outline of the shoes.

Used mainly as a gimmicky marketing tool, it was a common fixture in shoe stores during the 1930s, 1940s and 1950s. A typical unit, like the Adrian machine shown here, consisted of a vertical wooden cabinet with an opening near the bottom into which the feet were placed.

Most units also had a push button timer that could be set to a desired exposure time. The most common setting was 20 seconds.

Medical Patent Worst for Operator

A 20 second dose of low level radiation won't kill you. But multiple doses every day for a few years will. This patented machine wasn't nearly as dangerous to the customer as it was for the shoe salesman.

Ad for the Fluoroscope Shoe Fitting Machine

For example, to show how a shoe fit many salesperson would put their hands into the x-ray beam to squeeze the shoe during the fitting. As a result, one saleswoman who had operated a shoe fitting fluoroscope 10 to 20 times each day over a ten year period developed dermatitis of the hands.

One of the more serious injuries linked to the operation of these machines involved a shoe model who received such a serious radiation burn that her leg had to be amputated.

This is one medical patent that goes down amongst the worst of the century.

Medicine, drugs, genes and the death of a patent niche?

John Rizvi — Fri, 05 Nov 2010 15:14:11 -0500

Inventors pursuing medical patents involving genes should listen to this...

On October 29^th, the federal government reversed a longstanding policy by saying that human genes are part of nature and therefore cannot be patented. While the U.S. Patent and Trademark Office is not changing its rules for the time being, this decision may reverse the nearly 30 year old legal precedent of patenting parts of nature.

It all started with a March 29^th decision by a Judge Robert W. Sweet that invalidated seven patents related to the genes BRCA1 and BRCA2, whose mutations have been associated with cancer.

The patents were held by Myriad Genetics and the University of Utah Research Foundation, who charged $3,000 to perform tests on women to determine whether or not BRCA1 or BRCA2 genes would lead to mutations which could lead to breast and ovarian cancers.

You Can't Patent "Natural"

The main argument in this medical patent case is what is natural and what is not. The government claims that since genes are natural, you can patent them any more than you could patent an apple. A government brief from this case states:

"the chemical structure of native human genes is a product of nature, and it is no less a product of nature when that structure is ‘isolated' from its natural environment than are cotton fibers that have been separated from cotton seeds or coal that has been extracted from the earth."

Government critics are singing a different tune...

Long Term Innovation Hampered by No Patent Ruling?

Critics claim the government's anti-patent view of genes will put people in danger. Denying patents – they say – will hamper experimentation and development of diagnostic tests and drugs to treat specific genes. The long term implications being less treatment options for people with rare diseases.

The government insists prohibiting patents on parts of nature would not adversely affect the medical or biotechnology industry. And patents for man-made manipulations to DNA could still be approved.

Who is right? Only time will tell.

What Medical Industry Inventors can Learn from New Apple Patent

John Rizvi — Sat, 30 Oct 2010 18:01:22 -0500

Inventors in the medical device field may want to pay attention to a new patent awarded to Apple.

Titled "Nitriding Stainless Steel for Consumer Electronic Products", it describes a cost-effective system that would place a layer of nitride atop a stainless steel exterior. This would add a durable scratch and impact resistant surface to stainless steel.

There are other coatings that add these benefits to stainless steel, but they also usually mask the natural surface color and texture of stainless steel. For example, titanium nitride coating is a metallic gold color.

Why this is Important for Inventors in the Medical Field

Because stainless steel is used everywhere in the medical industry, including...

Scalpels
Clamps
Scissors
Screws
Replaceable joints
Trays

And any other number of medical devices. Do you think any of these products could benefit from a more durable scratch and impact resistant surface?

Questions To Help You Come Up With The Next New Medical Device Patent

Obviously you can't claim a patent for adding nitride to stainless steel operating equipment (Apple now owns the rights to this application), but there are a few lessons you can learn from them. As a medical device patent attorney focusing on medical patents and dental patents, I've come up with a couple questions you might want to ask yourself...

Medical Device Question #1: How could I improve an existing product?

Apple didn't invent anything brand new here. They just found new process that makes stainless steel more durable...which makes their products better. For a new inventor, this is one of the easiest ways to come up with new inventions.

Medical Device Question #2: What are the users used to?

Does your application or invention change the way the product looks so much that it won't be used? I highly doubt patients care if the knives cutting them open are silver or gold, but the doctors who use them have a built in way of identifying their tools.

If they are used to using silver tools, and your coating makes them pink...will they still use them? Even if they are better?

Asking yourself these two questions will ensure your invention qualifies for a patent...AND...that you have a marketable product to sell.

How to Ensure the Success of Your Dental Patent by Treating Disease

John Rizvi — Fri, 22 Oct 2010 09:26:22 -0500

A new patent-pending mouthwash may solve the needs of 25 million consumers. And at $10 a pop, this could be a brand new $250-$500 million per year industry. If you have an idea for the dental field, then following this company's advice could be your golden ticket.

Patents on Dental Products

I just finished reading a web article on Dentistry IQ - click on the link for the dental patent article - about Orazyme Dr Mouth Mouthwash.

According to the article, dry mouth:

"…is caused by various diseases and their treatments, stress, vitamin deficiencies, and by hundreds of common medications ranging from antidepressants to antihistamines. One in five people will experience its effects at some point.

Dry mouth isn’t just a matter of a dry, sticky uncomfortable feeling, cracked lips, rough tongue and the sensation that the teeth are perpetually dirty. It can be dangerous by affecting appetite, the ability to chew and swallow and digestion. In addition, dry mouth promotes tooth decay and gum disease, which are linked with other systemic diseases."

The article continues by explaining how the mouthwash contains two patent-pending technologies designed to help combat dry mouth.

The first one is a formula that "… features seven natural oral enzymes that remain bioactive through a patent-pending delivery system." The second is a "… patent-pending MIM Salzyme Metal Ion Management technology to help protect the mouth’s immune functions."

Three Golden Rules for Dental Patents

As an aspiring inventor, there is much you can learn from this new dental product. In fact, after reading the article I came up with three questions you can ask yourself after coming up with an idea.

Patent Question #1: Who is your audience? Apparently, over 25 million people are affected by dry mouth. Ask yourself, does my idea cater to a large enough audience to be profitable?

Patent Question #2: What is the problem? Dry mouth not only sounds uncomfortable, but it can lead to worse problems like, "tooth decay and gum disease". Ask yourself, does your product address a problem?

Patent Question #3: What's the urgency? Some problems can be put off or ignored, say a leaky faucet or squeaky door hinge. However, a problem that causes daily frequent pain (like dry mouth) is much harder to ignore. Ask yourself, what urgent problem can my product solve?

By creating a dental product that caters to such a large audience with an urgent problem, Orazyme is ensuring their success in the market. If you want to increase the odds of a marketable idea, make sure you ask yourself these three questions before pursuing a patent for your dental product.

How Medical Research Leads to New Patent Ideas

John Rizvi — Sun, 17 Oct 2010 20:20:26 -0500

A new patent pending medical device – based on scientific research – proves even simple innovations to existing products can be very lucrative.

Surgical masks haven't changed too much since 1918. It was the year of the Spanish Flu pandemic, and surgeons adopted cotton gauze masks during surgery to protect themselves from patient diseases.

The interest in masks as germ barriers was based on the work of Joseph Lister, who developed asuccessful system of antiseptic surgery (based on Louis Pasteur's' at the time controversial germ theory).

Since then, there has been much innovation in surgical masks. Lighter materials. More comfortable straps. Anti-glare strips. And of course, bacterial filtration. All worthy of new patents.

A New Patent for an Old Medical Invention

Despite all the new additions, one major problem remained…unique facial features.

Since surgical masks are a mass-produced item, there is no possible way for them to perfectly fit every face. And surgical masks that do not have a completely air-tight fit do not completely prevent the spread of germs.

A new medical patent aims to change that.

I recently came across a press release about a patent from Cantel Medical Corporation for a new type of surgical mask. And it shows how medical research can lead to new patents. Click here if you would like to read the press release. One paragraph in particular reveals how this new patent resulted directly from a medical study:

A recent study, published in the September 2010 issue of the American Journal of Infection Control quantified the ability of medical face masks to minimize the spread of infection. The study, entitled "Quantifying Exposure Risk and Mask Protection," found that a tighter-fitting mask may offer as much as 100-fold greater infection control benefit than standard, loose-fitting masks.

The press release goes on to explain how ill fitting masks are "rolling out a red carpet for dangerous infectious material to bypass the mask" and that proper fitting face masks are cheap insurance against infectious disease.

Takeaways for the Medical Device Inventor

Studies and medical research are great starting points for possible medical patents for two reasons:

1. Facts and figures of what needs to be improved

Usefulness is one of the first criteria the patent examiners use to determine if an idea is patentable. The study mentioned above found that "tighter-fitting masks may offer as much as 100-fold greater infection control benefit than standard, loose-fitting masks."

2. Proof there is a need.

There isn't much good to a new medical or dental idea, unless there is a need, or demand for the innovation. Looking into medical studies is one way to try and keep your finger on the pulse of medical demand. Including a reference to the study in the patent application is sometimes a good idea and can be very persuasive to a Patent Examiner of this need.

Spending some time digging through medical research could give you the next big idea.

Golfer Reveals Quick Patent Tips for Medical Device Inventors

John Rizvi — Sat, 09 Oct 2010 14:16:15 -0500

One of the hottest areas for inventions is in the medical device field and as a Registered Patent Attorney experienced with patenting medical and dental products nationwide, I have spoken to hundreds of doctors, dentists, nurses and even some patients interested in securing patents on their innovations. Some of the best inventions (and most patentable) all share a tried and true formula for success.

This formula

Saves time
Lessens your initial investment
And maximizes the chances that your invention will be approved by the Patent Examiner assigned to your case.

Here's a quick story, that although has NOTHING TO DO WITH MEDICAL OR DENTAL PATENTS, goes a long way to illustrate a simple formula uncovering patentable and profitable niches in the market.

Patent Lessons from a Golfer

I just finished reading a short article on South Carolina golfer and inventor Michael Owens (http://tinyurl.com/368xxma). Owens has a patent pending on a device that securely holds personal golf GPS devices and laser rangefinders in place on golf carts.

The device that holds the GPS on golf carts only took him several months to create, test and refine. With an outstanding order of 1,200 units at $29.95 each, Owens will just about cover his initial $45,000 investment.

Less than a year and already his idea is paying off. In terms of bringing an idea to market, that’s almost lightening speed!

The Easier Path to Patents

The inventor trick Owens used to quickly create a profitable invention is simply finding a better way to use an already wildly successful product.

Here's how he did it…

First, Owens found a product that people are already using.

If you are a golfer, you already know GPS units and laser range-finders are all the rage on the links. By linking his product to something that people use and are familiar with, Owens greatly increased his chances of patenting a marketable product.

Second, find a way to make that product easier to use.

In this case, Owen saw his friends fumbling with the GPS units in their pockets, in cart cupholders, seats or open spaces in the dashboard area. By creating a sturdy magnet-based GPS holder – that also didn't need to be removed constantly – Owens took a great product and made it better.

And if his patent application goes through, he will have the right to prevent anyone else from making, using, or selling his idea. A legal monopoly that he can charge a royalty percentage or outright sell to another.

Keep these two points in mind next time you are working on your next big idea.

Medical Patent Mistakes: Two Ways Physicians Sabotage the Profitability of their Intellectual Property

John Rizvi — Sat, 02 Oct 2010 18:35:21 -0500

Are you a doctor with an idea for an invention that could change the face of modern medicine…treat patients better, faster or cheaper…and (hopefully) fill your pockets with riches beyond the dreams of avarice?

If so, then you should know about a little "loophole" in the patent law that could negate the patentability of your inventions.

Here's the story: "John" is a doctor who has an idea for a product that will lower blood pressure. After a few months of tinkering in his garage, John has his invention in working order.

For two years John tests and improves his invention. During this time he also writes a few articles on the benefits of his new invention. And outlines a case study on his website. After John gets everything in working order, he decides to patent his invention…only to find out the patent is denied.

Why Patents Get Rejected

According to patent law to qualify for a new patent, inventions must be "novel". This means it does not exist in the "prior art," which includes publicly available written information or products that have been publicly used or sold.

The problem is that "prior art" is a very vague term.

Anything that could put your invention into the public mind (including simply publishing articles or using it in public) could be enough to qualify it as "prior art" and prevent you from exclusively cashing in on your idea.

With that in mind, here are the two mistakes John made.

Patent Mistakes

Mistake #1: Publicly Using the Invention – You should be particularly careful regarding public use, as the law does not require a high level of public exposure.

Mistake #2: Publishing the Inventive Idea – "Prior art" includes (among other things) any publication describing an invention that was published more than one year before filing a patent application covering the invention.

Even though the United States permits a one-year grace period in which to file a patent application, it is still prudent to file a patent application before selling, offering to sell writing about or publicly using the invention.
