Al Clark, Associate

A straight shooter committed to adding value

Prior to becoming an attorney and joining Patterson + Sheridan in 2004, Al Clark worked in the petrochemical industry as a plant manager for a metal fabrication and machine shop. This experience gave him a deep understanding of how mechanical parts are created and assembled, which he draws upon to relate to engineers and inventors, whether discussing semiconductors or robotics.

Al believes good lawyering is about adding value whenever possible, from the beginning to the end of every client engagement. Clients appreciate his straightforwardness when he explains legal options and their business implications — both good and bad — in layman’s terms, ensuring everyone involved is on the same page.

Starting with the basics, then branching out for broader protection

Al approaches patent applications by first getting a high-level understanding of the products and processes in their intended form, then diving into the technical specifics. This method allows him to quickly determine the patentability of the invention, then think through any design-arounds to try and capture for broader IP protection.

He has a two-pronged approach to drafting applications as well — one that benefits clients long after a patent has been issued. By providing both technical details that satisfy patent examiners and plain language even jurors can understand, Al ensures his clients receive robust protection upfront as well as cost savings in the event of future litigation.

International and domestic mechanical experience

Al’s deep knowledge of mechanical devices and materials manufacturing is apparent in his work around the globe. As an attorney practicing foreign and domestic patent law, he has worked largely with clients in Asia on products such as semiconductor and flat-panel displays, electromechanical devices, LED and LCD screens.

In his spare time, Al enjoys outdoor activities as well as old-fashioned blacksmith work, metal artwork and welding.
