Facts

K Tech Telecommunications Inc. filed a patent infringement against Blonder Tongue Laboratories Inc., R.L. Drake Holdings LLC, R.L. Drake LLC, and RLD '69 LLC. The disputed patents, entitled "Digital Television Translator with PSIP Update" related to the systems and methods for updating channel information in digital television signals. Both sides moved for summary judgment.

PLAINTIFF'S CONTENTION: Plaintiffs contended that defendants infringed on its patents.

DEFENDANTS' CONTENTIONS:
Defendants contended that the disputed patents were invalid because they were "anticipated by prior invention." Defendants further contended that the disputed patents were invalid as "obvious," and were unpatentable.

Result

U.S. District Court Judge R. Gary Klausner granted defendant's motion for partial summary judgment that the disputed patents were invalid. The judge denied K Tech's motion for summary judgment. After the summary judgment decision, Plaintiff K Tech requested and received an Order dismissing its action with prejudice. K Tech has since filed an appeal to the Court of Appeals for the Federal Circuit, where the matter is pending.
