Patent Eligibility: Is your invention eligible for patent protection?
The Supreme Court landmark decision concerning patent eligibility in Alice Corp. v CLS Bank International (decided June 19, 2014), brought to the forefront Section 101 of the U.S. Patent Act, which controls what types of inventions are eligible for patent protection. The outcome of this decision established a two-part test called the Alice Test, which specifically addresses software patents.
The Patent Act of 1790 was the first patent statute passed by the federal government of the United States. Section 101 provides that, “whoever invents or discovers any new and useful process, machine, or composition of matter, or any new and useful improvement thereof, may obtain a patent.” This statutory language provided little guidance.
Over time, it had become accepted that abstract ideas, laws of nature, and natural phenomena were ineligible for patent protection based on judicial exceptions created by the Supreme Court. Despite the broad language of the Patent Act, non-statutory exceptions were made.
It also became very difficult to distinguish between a patent claim that is attempting to cover an abstract idea or a natural phenomenon and a patent claim that is attempting to cover a patentable application of that same idea or phenomenon.
The proper test for analyzing inventions under Section 101 is the Alice test, with step one ensuring the invention can be grouped into one of the four categories of invention.
- PROCESS (initially classified as Art in 1790, and replaced in 1952): A process is an action. The Supreme Court defines process as “an act or series of acts, performed upon the subject-matter to be transformed and reduced to a different state or thing.”
