Infringing Parties

Paymentech sought declaratory judgment of non-infringement after BMC demanded licensing of 5,718,298 & 5,870,456; patents claiming processing debit transactions without using a personal ID number (PIN). BMC's problem, besides being dumb enough to provoke a DJ action, was that Paymentech by itself did not infringe the process claims; it took firms downstream, unrelated to Paymentech, to complete the claimed invention. The district court granted summary judgment of non-infringement. In a thoughtful no-brainer, the appeals court affirmed, marking guidelines for infringement when multiple parties are involved, and a cautionary note for claims drafting.

BMC Resources v. Paymentech (CAFC 2006-1503)

The case presents the issue of the proper standard for joint infringement by multiple parties of a single claim. As the parties agree, Paymentech does not perform every step of the method at issue in this case.

Direct Infringement

Infringement requires, as it always has, a showing that a defendant has practiced each and every element of the claimed invention. Warner-Jenkinson, 520 U.S. at 40 (element-by-element analysis for doctrine of equivalents). This holding derives from the statute itself, which states “whoever without authority makes, uses, offers to sell, or sells any patented invention within the United States, or imports into the United States any patented invention during the term of the patent therefor, infringes the patent.” 35 U.S.C. § 271(a) (2000). Thus, liability for infringement requires a party to make, use, sell, or offer to sell the patented invention, meaning the entire patented invention... For process patent or method patent claims, infringement occurs when a party performs all of the steps of the process. Joy Techs., Inc. v. Flakt, Inc., 6 F.3d 770, 773 (Fed. Cir. 1993).

Indirect Infringement

Where a defendant participates in infringement but does not directly infringe the patent, the law provides remedies under principles of indirect infringement... Indirect infringement requires, as a predicate, a finding that some party amongst the accused actors has committed the entire act of direct infringement. Dynacore Holdings Corp. v. U.S. Philips Corp., 363 F.3d 1263, 1272 (Fed. Cir. 2004).

Masterminding Infringement

These rules for vicarious liability might seem to provide a loophole for a party to escape infringement by having a third party carry out one or more of the claimed steps on its behalf. Cross Med. Prods. v. Medtronic Sofamor Danek, 424 F.3d 1293, 1311 (Fed. Cir. 2005). To the contrary, the law imposes vicarious liability on a party for the acts of another in circumstances showing that the liable party controlled the conduct of the acting party... A party cannot avoid infringement, however, simply by contracting out steps of a patented process to another entity. In those cases, the party in control would be liable for direct infringement. It would be unfair indeed for the mastermind in such situations to escape liability.

Inducing Infringement; Contributory Infringement

This court acknowledges that the standard requiring control or direction for a finding of joint infringement may in some circumstances allow parties to enter into arms-length agreements to avoid infringement. Nonetheless, this concern does not outweigh concerns over expanding the rules governing direct infringement. For example, expanding the rules governing direct infringement to reach independent conduct of multiple actors would subvert the statutory scheme for indirect infringement. Direct infringement is a strict-liability offense, but it is limited to those who practice each and every element of the claimed invention. By contrast, indirect liability requires evidence of “specific intent” to induce infringement. Another form of indirect infringement, contributory infringement under § 271(c), also requires a mens rea (knowledge) and is limited to sales of components or materials without substantial noninfringing uses.

Careful Claims Drafting to Capture Infringement

The concerns over a party avoiding infringement by arms-length cooperation can usually be offset by proper claim drafting. A patentee can usually structure a claim to capture infringement by a single party. See Mark A. Lemley et al., Divided Infringement Claims, 33 AIPLA Q.J. 255, 272-75 (2005). In this case, for example, BMC could have drafted its claims to focus on one entity. The steps of the claim might have featured references to a single party’s supplying or receiving each element of the claimed process. However, BMC chose instead to have four different parties perform different acts within one claim. BMC correctly notes the difficulty of proving infringement of this claim format. Nonetheless, this court will not unilaterally restructure the claim or the standards for joint infringement to remedy these ill-conceived claims. See Sage Prods. Inc. v. Devon Indus. Inc., 126 F.3d 1420, 1425 (Fed. Cir. 1997) (“[A]s between the patentee who had a clear opportunity to negotiate broader claims but did not do so, and the public at large, it is the patentee who must bear the cost of its failure to seek protection for this foreseeable alteration of its claimed structure.”)

Computer network claims are typical of claims that may involve multiple parties. There is a common strategic decision point for claims drafters in areas of potentially distributed process: point of view. In a client-server relationship, claims from the server viewpoint likely involves distributed actions, that is, on multiple computers; whereas claims from a client point of view are readily oriented to a single machine.

Another claims-drafting decision point is method versus machine. Software method claims are ubiquitous because device claims rope in the computer, which a software maker may not make, and thus not directly infringe.
