Canon Inc. and Canon U.S.A., Inc. today announce final victory in their defense of a long-term patent dispute against Technology Properties Limited LLC (TPL) and MCM Portfolio LLC (MCM). In March 2012, Plaintiffs TPL and MCM commenced litigation against Canon in both the U.S. International Trade Commission (ITC) and the U.S. District Court, accusing nearly 200 Canon products of infringing U.S. patents relating to flash memory card readers. In December 2013, Canon prevailed at the ITC on grounds of non-infringement. Additionally, in September 2016, the district court ruled in Canon's favor and held that none of Canon's accused products infringe any of the asserted claims of the patents-in-suit. Canon then sought—and was awarded—its attorneys' fees in the amount of nearly $1.8 million (USD).
In early 2017, Plaintiffs appealed both the district court's ruling and the fees award to the U.S. Court of Appeals for the Federal Circuit. On April 11, 2018, the Federal Circuit affirmed both the district court's non-infringement determination and its award of attorneys' fees, and the Plaintiffs chose not to appeal the affirmance to the Supreme Court, resulting in an across-the-board victory for Canon.
The Federal Circuit's decision caps a six-year litigation during which Canon successfully defended its products at nearly every level of the U.S. judicial system. Canon recognizes and respects intellectual property rights, but as this litigation demonstrates, Canon also remains committed to vigorously defending itself against false and frivolous allegations of infringement of others' intellectual property.
