Consensus Sales LLC, Apple Inc., and Robert Bosch GmbH are the leading companies. The listed firms are VLP Law Group LLP, Apex Attorneys at Law, LLP, and CANTOR COLBURN LLP. The long median timing is the primary operational consideration for practitioners, who may need to align continuation, amendment, and client expectation decisions with extended prosecution.
