Eastern District of Virginia Grants Summary Judgment of Noninfringement to Adobe

May 21, 2015

Reading Time : 1 min

TecSec filed its patent infringement lawsuit in February 2010 against 13 separate defendant groups, including Adobe, IBM, SAP AG, Cisco Systems, Oracle, EBay and PayPal, asserting infringement of 11 patents with a total of 380 claims in the field of computer encryption. Earlier in the case, the court stayed proceedings against all defendants except IBM.

After lengthy discovery, including IBM’s production of 7 million pages of documents, 40 depositions and 55 customer subpoenas, IBM moved for summary judgment of noninfringement, arguing that TecSec’s claims failed as a matter of law because the products did not perform every step of the asserted method patents and that it never sold products that used the entire system claimed by the patents. The court granted IBM’s motion in March 2011. The court’s summary judgment was appealed and then affirmed in part on appeal.

Adobe then moved for summary judgment in October 2014. In granting the motion, the court held that Acrobat’s Adobe software does not infringe TecSec’s patents because Adobe generates encryption dictionaries differently. Specifically, the court held, “TecSec has not raised a genuine dispute of material fact establishing that Acrobat performs the required ‘selecting’ step because it is undisputed that a user of Acrobat does not select the encryption dictionary.”

TecSec, Inc. v. IBM Corp., case number 10­dv­00115 (United States District Court for the Eastern District of Virginia).

In a precedential and sua sponte Director Review decision, USPTO Director Squires recently vacated three related institution decisions nearly six months after institution where a district court later found the challenged claims invalid. Because the fourteen-day deadline to request Director Review of the institution decisions had passed, the Director used this opportunity to formally extend the deadline in two ways. First, he extended the fourteen-day deadline under 37 C.F.R. § 42.75(c)(1) to thirty days, which “puts requests for Director Review of decisions to institute trial on equal footing to requests for Director Review of final decisions or decisions not to institute trial.” Second, he outlined certain “exceptional circumstances” that warrant a further extension of the deadline to account for changes in the case that “surface after the deadline.” In the case at hand, the Director found the district court’s invalidity finding to be such an “exceptional circumstance” and ultimately initiated review and vacated the institution decisions on that basis.

The Supreme Court unanimously held that for a complaint of induced infringement, a patent owner must allege that the accused infringer took affirmative, not passive, steps to encourage direct infringement. Thus, where a generic drug has a skinny label, to induce infringement of the carved-out patented use of the drug, the generic company must have taken steps that were designed to cause others to perform the patented use, not just steps that could cause such conduct.
