Many successful businesses were started by entrepreneurs who turned an invention into a viable product or service. It is hard to imagine the success of our economy, in fact, our society, without the system of inventions and patent protection. Our Founding Fathers recognized the importance of innovation and added patent protection to our Constitution, in Article I Section 8. From the very first patent that President George Washington signed in 1790 to the ten millionth patent, since the current numbering system started in 1836, issued on June 19, 2018, the patent system has been fueling the technological and economic growth of our nation.
The word “patent” means “open” and by granting an inventor the right to exclude all others from making, using, or selling the invention, the patent allows an inventor to literally open up his invention to the world. Such an open patent publication lets others learn from it and improve upon the idea. Once an improvement is made, the improved invention is then patented and left open to the world for further improvement. This cycle of improvement is the engine of innovation for our technology and economy.
To encourage innovation, the courts held that the threshold for patent eligibility was very low and easy to meet, leaving it to the other patent requirements to determine the invention’s patentability. In recent years, however, the Supreme Court made several imprecise decisions that ended up creating a quandary in the field of patent eligibility.
In response, the U.S. Patent and Trademark Office (USPTO) announced new guidance for determining patent eligibility.
Patentability Requirements and Patent Eligibility
For an invention to be patentable, it must meet certain requirements:
- “Novelty.” The invention has to be new. It would be hard to convince a patent examiner that one has invented the wooden chopsticks, which have been in general public use for thousands of years. (Incidentally, however, a few dozen patents have been issued for various forms of chopsticks including “gravity chopsticks” that supposedly avoid germs and dirt.)
- “Utility.” The invention must be useful to the society. One cannot get a patent for a chemical compound whose sole function is to cause a massive headache, for example.
- “Non-obviousness.” An invention is not patentable if it is an obvious improvement from an existing invention. For instance, one cannot get a patent by taking an existing patent for a bicycle and “improving” it by adding a light for night-time biking. Although no longer the standard, Justice Douglas succinctly described non-obviousness: an invention “must reveal the flash of creative genius!”
In addition to meeting the novelty, utility, and non-obviousness requirements, an invention has to be in one of the following four categories to be eligible for patent consideration:
- “Process” such as a method for conducting secure financial transactions over the internet by authenticating a customer’s identity;
- “Machine” such as a new vacuum cleaner that roams around a room and cleans it;
- “Manufacture” such as a new snow shovel that requires less effort to shovel snow; and
- “Composition of matter” such as a new drug or a new glue.
Since the Patent Act of 1790 through the Patent Act of 1952 and the America Invents Act (or “Patent Reform Act of 2011”), just about any manmade invention was eligible for patent consideration. An inventor had a clear idea of what would qualify as patent eligible. In recent years, however, patent eligibility has become murky and confusing because of a few imprecise decisions by the Supreme Court.
U.S. Supreme Court Decisions
In 2012, the Supreme Court shocked the world of patent law with its ruling in Mayo Collaborative Servs. v. Prometheus Labs. In an opinion by Justice Breyer, the Supreme Court unanimously ruled that “basic tools of scientific and technological work” were not eligible for patent and that “one must do more than simply state” the law of nature. The Court was concerned that granting exclusive rights to natural phenomena would impede innovation.
More shocking than the ruling itself was the Court’s confusing explanation that, to be patent eligible, an invention required an “inventive concept” to ensure that the claim amounts to “significantly more” than a claim upon a natural law itself. The Court did not explain what “inventive concept” was, however.
In 2014, in an opinion by Justice Thomas for Alice Corp. v. CLS Bank Int’l, the Supreme Court doubled down on the Mayo test and expanded it to exclude abstract ideas from patent eligibility. The Court distinguished between basic “building blocks” and inventions that integrate them into “something more,” and created a test for determining patent eligibility: First, determine whether the claims are directed to one of the patent-ineligible concepts. Second, if so, determine whether the claims include additional elements that transform the claims into patent-eligible applications. Unfortunately, however, this two-step Alice test added to the confusion over patent eligibility.
Since the 1952 Patent Act, the courts held that patent eligibility was easy to meet and that the other requirements – novelty, utility, and non-obviousness – would do the necessary screening of claims. By overturning precedent cases and ignoring legislative history, the Supreme Court created confusing restrictions that effectively render some of the most exciting scientific discoveries and technological advances of the twenty-first century ineligible for patent protection. Things like personalized medicine, artificial organs, artificial intelligence, and medical diagnostics are not patent eligible.
Many in the patent field, including several Federal Circuit judges, expressed their deep concerns over this confusion. Some have called the Supreme Court decisions extraordinarily-shortsighted and, specifically, the Mayo opinion the worst opinion issued in patent law.
The USPTO Proposal – Thank you, Mr. Iancu!
Since Alice, the Supreme Court has denied a long line of patent appeals involving the question of patent eligibility, sidestepping opportunities to clarify what some call “unintelligible test for patent eligibility.” As major industry groups such as the American IP Law Association (AIPLA) and Intellectual Property Owners Association (IPO) joined law professors and industry watchers in voicing their concerns, and with no sign of resolution from the Supreme Court or the Congress, the USPTO proposed new guidance on patent eligibility.
In his speech at the IPO Annual Meeting in September 2018, the new director of the USPTO Andrei Iancu proposed the following steps for determining patent eligibility.
First, Iancu defined “basic tools of scientific and technological work” as:
- “Pure discoveries of nature, such as gravity, electromagnetism, DNA, etc.” (citing Association for Molecular Pathology v. Myriad Genetics, Inc.);
- “Fundamental mathematics like calculus, geometry, or arithmetic per se” (citing Gottschalk v. Benson);
- “Basic ‘methods of organizing human activity,’ such as fundamental economic practices like market hedging and escrow transactions” (citing Bilski v. Kappos and Alice); and
- “Pure mental processes such as forming a judgment or observation.”
Second, Iancu is most concerned with eligibility issues surrounding abstract ideas and he proposed three categories of abstract ideas:
- “Mathematical concepts like mathematical relationships, formulas, and calculations”;
- “Certain methods of organizing human interactions, such as fundamental economic practices, commercial and legal interactions; managing relationships or interactions between people; and advertising, marketing, and sales activities”; and
- “Mental processes, which are concepts performed in the human mind, such as forming an observation, evaluation, judgment, or opinion.”
Third, Iancu explained that once the subject matter of the claims is determined to be a “process, machine, manufacture, or composition of matter,” a patent examiner would determine if the subject matter is within one of the enumerated categories of exceptions. According to Director Iancu, “This is the new approach. . . . If the claims do not recite subject matter falling into one of these categories, then the . . . [patent eligibility] analysis is essentially concluded and the claim is eligible.”
Conclusion
Many in the industry are optimistic and hopeful that the boundaries set by the new guidance will minimize uncertainty and encourage innovation. For inventors and entrepreneurs, this can only be good news.
Each year the USPTO receives over 600,000 patent applications. Although China receives more patent applications (1.38 million) than the U.S., followed by Japan (318,000), South Korea (204,000), and Germany (68,000), the U.S. patent is the most prestigious and coveted patent in the world. It has been a powerful engine for innovation, often with worldwide influence.
The new USPTO guidance on patent eligibility may not be perfect, but, given the constraints of judicial precedent, it is a reasonable approach and a significant step in the right direction. Combined with the creativity and determination of entrepreneurs, the new guidance will help keep the engine of innovation running at full speed.
