How can a treatment or prophylaxis limitation qualify for consideration in Step 2A Prong Two?
For a treatment or prophylaxis limitation to qualify for consideration in Step 2A Prong Two, it must meet certain criteria. According to MPEP 2106.04(d)(2):
“Examiners should keep in mind that in order to qualify as a ‘treatment’ or ‘prophylaxis’ limitation for purposes of this consideration, the claim limitation in question must affirmatively recite an action that effects a particular treatment or prophylaxis for a disease or medical condition.”
Examples of qualifying limitations include:
- “Administering amazonic acid to a patient”
- “Administering a course of plasmapheresis to a patient”
Conversely, limitations that do not qualify include:
- Intended use statements (e.g., “for treating a patient”)
- Field of use limitations (e.g., “a pharmaceutical composition”)
- Non-specific actions (e.g., “prescribing a topical steroid to a patient with eczema”)
