On April 19, the USPTO issued a memo with an update on subject matter eligibility guidance.  The memo explains changes to Subject matter eligibility rejections based on recent case law (Berheimer & Aatrix).  Determining that something is “well-understood, routine, and conventional” is a factual matter and must be supported in writing with one of the following:

  1. citation to an express statement in the specification or to a statement made by an applicant during prosecution;
  2. citation to one or more of the court decisions discussed in MPEP § 2106.05(d)(II);
  3. citation to a publication can be used that demonstrates the well-understood, routine, conventional nature of the additional element(s); or
  4. taking official notice.

There is a lot more detail is the official memo, it’s worth a read.

This is welcome news to practitioners that are dealing with subject matter eligibility issues.
