The purpose was to remove ambiguity about the understanding of the same. These changes consolidate several judgments passed by the Supreme Court for many patent cases with unique situations. These cases were judicial exceptions and the new rules clear any confusion regarding the judgments for those cases. The new rules will aid the examiners to be more certain

Subject Matter Eligibility: A Quick Understanding

Subject Matter eligibility outlines the rules which define whether or not an invention meets the patentability criteria. The 35 U.S.C 101 law defines the patentable subject matter in the following way:

“Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof may obtain a patent therefor, subject to the conditions and requirements of this title.”

A patent examiner follows the Alice/Mayo Test and views this statement in 2 steps. The first step checks whether the invention is a process, machine, manufacture or composition of matter. The second step is that the invention should not fall into any exception recognized by the courts. These exceptions mean that you cannot call laws of nature, physical phenomena or abstract ideas as inventions.

Subject Matter Eligibility: Why is Change Needed?

Despite these guidelines, there is room for confusion and interpretation in the understanding of judicial exceptions. There have been multiple patent cases where the verdict was incoherent with the 35 U.S.C 101. Therefore, it was difficult to apply a single standard judicial precedent in every case with maximum certainty.

Also, this set-up provides only a single-point reference to identity judicial exceptions. Therefore, identifying or eliminating a claim by comparing the current set of claims with a previous set has a lot of issues. This is because this process is time-consuming, error-prone and incoherent.

Subject Matter Eligibility: The Modifications

These changes address the shortcomings of the existing guidelines. It also ensures a more efficient and effective method for conducting the patent examination.

These changes focus mostly on Step 2A and 2B of the Alice/Mayo test. It explains that the subject matter that can be considered as an abstract idea by broadly grouping them into three categories. Also, it clarifies that an individual claim, with reference to the complete invention, is not a judicial exception if the claim in a certain scenario. That is, if the claim, along with additional elements, integrates a judicial exception into a practical application (Prong 1 & 2 of Step 2A).

Besides, an invention that is directed towards judicial exceptions may still be patent-eligible. However, there must be additional element(s) which will be examined independently in combination with the exception. Ultimately, their use in relation to the judicial exception should be unconventional and establish an inventive concept. This will make the invention patent-eligible.

The importance of these elements in comparison with the overall invention is not absolutely pivotal for determining eligibility. However, these elements should impose a meaningful limit on the exceptions and not just be a drafting technique. This is important in order to avoid objection (Step 2B).
