Apple Inc said on Friday that it filed a countersuit against Nokia, claiming that the Finnish cellphone maker is infringing 13 Apple technology patents.
The move follows a Nokia lawsuit filed in October accusing iPhone maker Apple of infringing 10 Nokia patents for technologies such as wireless data, speech coding and security. Apple did not reveal which patents were at issue or where it filed its lawsuit in a short statement announcing the case. “Other companies must compete with us by inventing their own technologies, not just by stealing ours,” Bruce Sewell, Apple's General Counsel said in the statement.
Nokia was not immediately available for comment.
