More on patents and employee rights
Recently we discussed a rather controversial suggestion about keeping the ownership of patents with the inventors, instead of forcing inventors to assign patents to their employers. One of the major objections to this idea is that it appears to stand outside the current thinking on patent law in the US. But a recent decision for a summary judgment in the US District Court Northern California District both suggests that the law doesn’t accept employers’ unhindered right to employees’ patents, and illustrates just how complex patent law can be in the US, where state codes and federal law can almost overlap.
In this ruling (a copy of which is purportedly here, but I can’t identify the provenance of this site) Judge James Ware granted a summary judgment to defendants who were being sued by Applied Materials. The defendants, according to this document, were employees of Applied, and signed various versions of an employment agreement that said, to quote one version:
"In case any invention is described in a patent application or is disclosed to third parties by me within one (1) year after terminating my employment with APPLIED, it is to be presumed that the invention was conceived or made during the period of my employment for APPLIED, and the invention will be assigned to APPLIED as provided by this Agreement, provided it relates to my work with APPLIED or any of its subsidiaries."
The defendants left Applied and went to work for another company, Advanced Micro-Fabrication Equipment. There, according to Applied, the defendants described or disclosed inventions within one year of their departure. Applied wished to claim the right to patents from these inventions. The defendants countersued, asking for a summary judgment that under California law, the clause in their employment contracts was anticompetitive, restricted their ability to pursue their careers, and was therefore void. The court this week granted their request for summary judgment, according to this document—in effect, saying that Applied had no legal claim on the inventions because the clause in their employment contract was in fact void.
This is a very specific circumstance—a case in which the customary demand that employees assign their patents extends not just to the period of employment, but to the subsequent year. So it does not speak to the vast majority of patent-assignment clauses. And the basis of the decision—that the clause restricts the former employees’ right to pursue their careers—is specific to California law, and says absolutely nothing about the rights of employees to inventions they create while working for a particular employer. So no jumping to conclusions here.
However—the decision does illustrate that the ability of employers to demand assignment is not unlimited. It is limited if it interferes with other laws, as in this case. And by inference, it is limited in time. A company cannot simply reach out of the past and demand rights to the work of a former employee. Both of these are important points, and are perhaps an indication that current attitudes toward patent assignment clauses can change.
In addition, the decision shows just how impossibly complex patent law has become. Here, a patent clause was struck down because it was judged to conflict with the California Business and Professional Code—a body of law that is specific to one state, and that has on the surface nothing whatsoever to do with patents. If Applied had been based in Oregon, or Ohio, or wherever, the defendants might have had no recourse. As the court’s ruling points out in another context, it is entirely possible that employees would surrender their patents on demand, having no easy access to counsel and no clue that they are protected under the business code of a state in which they no longer reside. It is a mess that cries out for clarification.
