Bill Conger is a patent prosecutor who is passionate about working with his clients and making extensive efforts to understand their inventions and technologies. As a patent lawyer and Co-Chair of Brooks Kushman's chemical practice, Bill instills trust and confidence in his clients. His clients know that they can rely on him to make important decisions that keep their best interests at heart at all times. When there are several alternative paths that can be taken, Bill is skilled at recognizing the one that makes the most business sense for his client. Bill makes extensive efforts to understand his client`s technology and their business goals, making frequent client visits, and even occasionally working on-site for extended periods. Bill works directly with inventors so that he can fully understand their inventions and maximize the scope of all related patents. As a result of his effectiveness and creativity, he has twice been named as a co-inventor on patents. Based on his experience as a former Director of Patents for BASF, Bill developed an extensive international practice, assisting foreign clients in filing applications for inventions first filed in other countries. Bill`s experience allows him to finesse the originally-filed foreign application to obtain the broadest possible protection in the United States, to reduce costs to the client, and to shorten prosecution as well. Bill also takes great pleasure in drafting original patent applications. He likens the process to writing the great American novel because it allows him to weave together a compelling persuasive argument that leaves the audience with enough information to understand the story being told, without encouraging them to start a new one. When not involved with technology or IP issues, Bill enjoys tennis, boating, and hunting for precious gemstones in various areas of the country, particularly the West and Northwest."
