Narrative Opinion Summary
This case involves a legal dispute between a patent holder (Perricone) and a pharmaceutical corporation (Medicis) over the alleged infringement of two patents related to skin treatment methods using ascorbyl fatty acid esters. Perricone sought summary judgment on the validity and infringement of U.S. Patent Nos. 5,409,693 and 5,574,063, while Medicis countered with motions challenging certain claims' validity on grounds of double patenting and anticipation by prior art. The court examined the standards for summary judgment, ultimately finding that Medicis's claims of invalidity were supported by clear and convincing evidence. It applied the doctrine of obviousness-type double patenting, determining that certain claims of the '063 patent were not patentably distinct from those in the '693 patent. Additionally, the court ruled that prior art anticipated multiple claims across both patents, referencing the Pereira disclosure, which inherently covered the methods claimed by Perricone. Consequently, the court granted Medicis's motion for partial summary judgment of invalidity and denied Perricone's motions for summary judgment. This decision effectively nullified the infringement claims, leading to a declaratory judgment of non-infringement in favor of Medicis.

Double Patenting Doctrinesubscribe to see similar legal issues
Application: The court applied the doctrine of obviousness-type double patenting to invalidate certain claims of the '063 patent, highlighting that these claims were not patentably distinct from those in the '693 patent.
Reasoning: Claim 9 of the '063 patent is declared invalid due to double patenting over claim 1 of the '693 patent. Claims 12 and 13 of the '063 patent, which are dependent on claim 9, do not introduce any new limitations compared to claims 3 and 4 of the '693 patent, resulting in their invalidity on the same grounds.
