Commscope Technologies LLC v SOLiD Technologies, Inc.

Commscope Technologies LLC v SOLiD Technologies, Inc.

EP850 is invalid for anticipation and obviousness over Oh, which discloses both single and multi-channel digital DAS with digital summing and multiple remote units. The patent claims are broad and not limited to single-channel arrangements. Expansion units and relevant network architectures were common general knowledge. SOLiD did not infringe as EP850 is invalid. The court lacks jurisdiction to allow amendment of EP626 after discontinuance of all proceedings in which validity was in issue.
