Intex Recreation Corporation v. Team Worldwide Corporation
42 F. Supp. 3d 80
D.D.C.2013Background
- Intex objected to Magistrate Judge Robinson’s claim-construction ruling on two terms in the ’469 Patent: socket and pump body.
- The ’469 Patent covers an air mattress with a built-in socket, a detachable electric pump with a pump body and an air outlet, and a battery case.
- Judge Robinson adopted a broad definition of socket as an opening that forms a holder for something; she also held pump body to be the main part of the pump.
- The court applies Phillips v. AWH Corp. and related authority to evaluate intrinsic evidence (claim language, specification, and prosecution history) before considering extrinsic sources.
- PTO reexamination findings and prosecution history are used to support a narrow construction of socket and aid interpretation of pump body.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| How should socket be construed? | Intex urges a narrow, detachable-connection meaning. | TWW advocates a broader meaning: an opening or hollow that forms a holder for something. | Socket construed narrowly as a structure that fits and detachably connects to an inserted part. |
| How should pump body be construed? | Pump body should include the housing surrounding other components. | Pump body is the main part of the pump, not necessarily including housing. | Pump body means the main part of the electric pump and is a separate element from the air outlet. |
| What evidence governs claim construction here? | Intrinsic evidence (specification/prosecution history) supports Intex. | Extrinsic evidence may be consulted but is less reliable. | Intrinsic evidence controls; extrinsic evidence given limited weight. |
| Does prosecution history limit the term socket? | Embodiments showing detachable connections inform the meaning. | Withdrawn embodiments should not broaden claim scope. | Prosecution history supports a detachable-connection reading for socket. |
