Source Vagabond Systems Ltd. v. Hydrapak, Inc.
753 F.3d 1291
Fed. Cir.2014Background
- Source appeals district court Rule 11 sanctions for filing a frivolous patent suit against Hydrapak over the ’276 patent (Widepac reservoir).
- Source was the assignee of the ’276 patent; Yonay and Shuman (Source’s counsel) signed the original and amended complaints.
- The district court construed the key term “slot being narrower than the diameter of the rod” and found Source’s proposed construction wrong.
- The court granted Hydrapak summary judgment of noninfringement and Rule 11 sanctions, and set attorney’s fees at $289,532.74 plus costs; the magistrate later added reconsideration costs to reach $200,054.00 in sanctions to Source.
- Source appealed the sanctions and the merits ruling; the appellate court affirmed.
- Key causal factor was Source’s reliance on an amended claim construction that added words not supported by the intrinsic record.
