WesternGeco LLC v. ION Geophysical Corp. (In re WesternGeco LLC)

Summary

The United States Court of Appeals for the Federal Circuit affirmed six Patent Trial and Appeal Board decisions finding claims in three WesternGeco patents unpatentable in inter partes review proceedings. The court held that substantial evidence supported the Board’s anticipation and obviousness determinations and that the proceedings were not barred under 35 U.S.C. § 315(b). The court also addressed the common-law meaning of privity and concluded that ION and PGS were not privies for purposes of the statutory time bar.

Holdings

1. ION and PGS were not privies within the meaning of § 315(b). Privity is a flexible, fact-dependent inquiry informed by common-law preclusion principles and bounded by due process; control is relevant but is not the exclusive test.
2. The IPR petitions were not barred by the one-year time limitation in 35 U.S.C. § 315(b).
3. The Board did not abuse its discretion in denying WesternGeco's request for additional discovery.
4. The term "predicting positions" means "estimating the actual locations" of streamer positioning devices and does not require use of behavior-predictive model-based control logic.
5. The Board correctly construed "control mode" to mean "operational state" and properly declined to add requirements that the mode be goal-oriented and automatic.
6. The Board correctly found claims directed to the feather-angle mode obvious over Workman.
7. The Board properly construed "global control system" as "a control system capable of overseeing and affecting the array of streamers and streamer positioning devices" and correctly found the challenged claims anticipated or, alternatively, obvious over the '636 PCT.
8. The Board properly found that WesternGeco failed to establish a sufficient nexus between the claimed inventions and its objective evidence of nonobviousness, and that the evidence would not overcome the strong showing of obviousness in any event.

Questions Presented

1. Whether the inter partes review petitions were barred under 35 U.S.C. § 315(b) because ION was a privy or real party in interest of PGS.
2. Whether the Board abused its discretion by denying WesternGeco additional discovery concerning the alleged privity relationship.
3. Whether the Board properly construed the claim term "predicting positions" in the '607 Patent.
4. Whether the Board properly construed the term "control mode" in the '520 Patent and correctly found the feather-angle claims obvious over Workman.
5. Whether the Board properly construed "global control system" in the '967 Patent and correctly found the challenged claims anticipated or obvious over the '636 PCT.
6. Whether the Board properly evaluated WesternGeco's objective evidence of nonobviousness.
