The solid technological underpinnings on which Sunstein’s IP platform is based promote a high degree of efficiency in all areas of its practice, including patents. The dedicated patent group applies a rigorously commercial mindset in carrying out its prosecution and portfolio management assignments; this translates into the creation of enforceable assets that also appeal to acquisitive companies and potential licensing partners. Bruce Sunstein sets the standard when it comes to patent quality; highly respected for his IP wisdom, he is regularly called on as an expert witness and arbitrator.
