This comment by 25 law professors, economists and former United States government officials was submitted to the European Union Commission in response to a “call for evidence” on the licensing, litigation, and remedies of standard-essential patents (SEPs). It details the principal concepts...

This contribution condenses the author’s previous detailed analyses of antitrust and patent policies in global smartphone markets. The discussion comprises three elements. First, it identifies the key constituencies in the smartphone ecosystem and the role each constituency plays in the...

This short contribution updates through 2018 the author’s prior empirical study on global innovation trends as indicated by USPTO patenting data during 1965-2015. The principal trends identified previously have largely continued, with the exception of a slight universal decline in annual...

Intellectual property licenses are commonly portrayed as a “tax” that limits access to technology assets, thereby stunting innovation by intermediate users and inflating prices for end-users. This presumptively skeptical view motivated postwar antitrust’s proliferation of per se rules...

Information technology markets in general, and wireless communications markets in particular, rely on standardization mechanisms to develop interoperable devices for rapid and secure data processing, storage and transmission. From 2G through the emergent 5G standard, wireless communications...

Intellectual property scholars and policymakers often assert that technology and creative markets suffer from “anti-commons” (“AC”) effects that restrain innovation within a web of conflicting intellectual property claims. A minority view asserts that market players have incentives and...

Scholarly and popular commentary often assert that markets characterized by intensive patent issuance and enforcement suffer from “patent thickets” that suppress innovation. This assertion is difficult to reconcile with continuous robust levels of R&D investment, coupled with declining...

Digital markets offer abundant free content but exhibit extreme concentration among content aggregation intermediaries. These characteristics are linked. In commoditized weak-IP markets, firms earn revenues by bundling free content for users with positively priced advertising services for firms....

Legal scholars have tended to approach the licensing of intellectual property rights with skepticism, calling for legal intervention to protect the public domain against purported encroachment by IP licensors. Recent decisions by the U.S. Supreme Court are consistent with this view. This...

Intellectual property rests on a simple incentive rationale: without imitation barriers, innovators rationally decline to invest. But this blanket proposition is incompatible with markets where innovation proceeds without substantial recourse to intellectual property and imitation is widespread....
