Ben esplin


Prior to founding Esplin & Associates, Ben was a partner at two different AMLAW 100 firms. Over the course of his career, Ben has had exposure to patent litigation, patent portfolio sales, and patent licensing. However, over time he has focused his efforts on patent portfolio strategy and patent application preparation and prosecution. Ben values clear communication in any complex undertaking and building or enhancing a patent portfolio is certainly an example of this principle. As a result, Ben strives to communicate clearly with business leadership, in-house counsel, and inventors to make sure that all stakeholders in a patent application and/or portfolio are aligned.
