I’ve got two new articles on patent reform out today, and by sheer coincidence, both of them are related to the work of law professor John Duffy. First, over at Ars Technica, I analyze John Duffy’s article at Patently-O, where he argued that the US Patent Office has shown a growing hostility toward software patents over the last couple of years. He seems to be right that the Patent Office is becoming more skeptical about software patents, but of course we have a difference of opinion about whether this is a good thing:
Duffy seems to regard the end of software patents as a calamity for innovative companies, but his argument is awfully thin. Duffy focuses on Google’s PageRank patent, which he has long regarded as a poster child for software patenting. He describes it as “surely one of the most famous and valuable of all modern software patents,” and suggests that the invalidation of Google’s patents would be a calamity for the company. Curiously, however, he never explains how Google benefits from this or other patents in its portfolio.
Google derives little, if any, of its revenue from patent royalties and has managed to dominate the search engine marketplace without suing its major rivals for patent infringement. Indeed, it appears that the primary function of Google’s patent portfolio is as a defensive stockpile to be used if any competitors should sue it for patent infringement. If that’s true, then the only real effect of software patent abolition on Google would be that the company could lay off its patent lawyers.
