Federal Circuit Further Validates Linear Technology’s Burst Mode® Patented Technology

Linear Technology Corporation (Nasdaq:LLTC), a leading supplier of high-performance analog integrated circuits, today announced that the United States Court of Appeals for the Federal Circuit (Federal Circuit) has issued its opinion in Linear's and Advanced Analogic Technologies, Inc.'s (AATI) cross appeals from the investigation that Linear brought against AATI at the United States International Trade Commission (Commission) directed to infringement of one of Linear’s power and battery saving patented technologies. The Federal Circuit found that AATI's 1143 and 1146 family of parts infringe Linear's U.S. Patent No. 6580,258 ('258 patent) and that Linear’s litigated claims 2, 3, and 34 are valid. The Federal Circuit also reversed the Commission's finding that AATI's 1151 and 1265 family of parts do not infringe Linear’s asserted method claim 34. Similarly, the Federal Circuit reversed the Commission's finding that Linear’s claim 35 was invalid and not infringed. The Federal Circuit's decision expands the scope of the exclusion order from the United States that the Commission issued against AATI to encompass their 1146 family of products and raises the possibility that the Commission might find the remaining accused AATI products infringe Linear’s patent as well.

John England, Linear's Corporate and IP Counsel, stated, "We are delighted with the Federal Circuit's decision which we maintain further validates Linear’s pioneering and patented Burst Mode^® battery and power saving technologies.”
