Narrative Opinion Summary
The case involves Plumtree Software, Inc., which filed a declaratory judgment action to challenge the validity of two patents held by Datamize, LLC, concerning an authoring system for computer-based information systems. The U.S. District Court for the Northern District of California sided with Plumtree, granting summary judgment by invalidating the patents under the on-sale bar doctrine per 35 U.S.C. § 102(b). Datamize's motion to dismiss for lack of subject matter jurisdiction was denied, as the court found a reasonable apprehension of an infringement suit by Plumtree. On appeal, the Federal Circuit upheld the jurisdictional finding but vacated the summary judgment, remanding the case for further proceedings regarding the merits. The court considered the applicability of the on-sale bar, examining whether a commercial sale or offer of the patented invention occurred before the critical date. The court applied the Pfaff v. Wells Electronics, Inc. test and found a lack of clear evidence to sustain the summary judgment. The case was remanded for further proceedings to address unresolved factual issues concerning the commercial offer and possible infringement of the apparatus claims, with no costs awarded.

Application: Datamize argued for the separate consideration of apparatus claims upon remand, which was permitted although not previously presented.
Reasoning: There is also a dispute regarding the district court's consideration of the apparatus claims of the '418 patent, with Plumtree arguing that Datamize cannot raise this issue since it was not presented previously.
Commercial Sale or Offer for Salesubscribe to see similar legal issues
Application: The court evaluated whether an actual commercial sale or offer of the patented invention occurred prior to the critical date, determining that further factual clarification was required.
Reasoning: The determination of whether MA made such an offer follows federal common law and the precedent set in Scaltech, where a commercial offer related to a patented process implicated the on-sale bar.
Declaratory Judgment Action Requirementssubscribe to see similar legal issues
Application: The court assessed whether Plumtree had a reasonable apprehension of facing an infringement suit regarding the '040 and '418 patents, finding that the totality of circumstances indicated such apprehension.
Reasoning: The court employs a two-part test to assess this controversy: (1) the patentee must have made an explicit threat or taken other actions that create a reasonable apprehension of an infringement suit for the declaratory plaintiff, and (2) there must be present activity by the declaratory plaintiff that could constitute infringement or a clear intent to engage in such activity.
On-Sale Bar Doctrine under 35 U.S.C. § 102(b)subscribe to see similar legal issues
Application: The district court ruled that the patents were invalid under the on-sale bar, as an agreement existed before the critical date, with MA receiving consideration for the kiosk's display.
Reasoning: The court found that an agreement to provide a method claim existed before the critical date, as evidenced by the January 17 meeting. MA received consideration for the kiosk's display, as it was granted a prime location at the trade show in return for waiving the fee.
