Patentees are continuing to move away from the single-patent model toward a model that involves multiple patents in multiple jurisdictions. Today, over 75% of patent applications rely upon at least one prior patent filing as a priority document. I expect that figure to grow based upon incentives coming from the recently implemented first-to-file regime. Over the past 10 years, most of the change has been in increased PCT filing and increased use of US provisional patent applications. In the US, the largest users of the provisional patent applications are some of the largest strategic users of the patent system, including Qualcomm, LG, Broadcom, Marvell, Google, Apple, Samsung, Univ of California, and Texas Instruments. More than 40% of patents with a US assignee (or US inventor owned) claim priority to a provisional application. Expect that figure to rise as well.
