It is utterly beyond me why we continue to have this identical conversation again and again.

Larry, if you want to document, for each of our projects, what standards and patents they implement, just friken do it. We are a do-ocracy. Submit a patch. Quit asserting that *someone* should do it. That is not how things get done here.

You have made it abundantly clear what you think should happen. Many people have made it clear what they think of your ideas. But if you want anything to happen, you have to submit a patch. You're not new here. You know how this works.

If Apache members or customers are much worried about liability for contributory patent infringement merely by redistributing some Apache software, read the below quotation from the 2014 Jury Instructions of the Federal Circuit Bar Association (and the cases listed there).


It seems that the distributor of an ASF software product that implements a widely-used, patent and copyright royalty-free W3C standard is not likely to be held liable as a contributory infringer for other miscellaneous patents that we later discover happen to read on that software.


That's usually good for ASF and distributors!


And it is another good reason to "advertise" in our NOTICE file that our software implements specific FOSS-compatible W3C standards capable of substantial non-infringing uses, in compliance with the new W3C license.







[Patent holder] argues that [alleged infringer] is liable for contributory infringement by contributing to the direct infringement of the [ ] patent by [insert name or other description of direct infringer]. As with direct infringement, you must determine contributory infringement on a claim-by-claim basis.

[Alleged infringer] is liable for contributory infringement of a claim if [patent holder] proves by a preponderance of the evidence:

(1)               [alleged infringer] sells, offers to sell, or imports within the United States a component of a product, or apparatus for use in a process, during the time the [ ] patent is in force;

(2)               the component or apparatus has no substantial, noninfringing use;

(3)               the component or apparatus constitutes a material part of the invention;

(4)               [alleged infringer] is aware of the [ ] patent and knows that the [products or processes] for which the [component or apparatus] has no other substantial use may be covered by a claim of  the [ ] patent or may satisfy a claim of the [ ] patent under the doctrine of equivalents; and

(5)               that use directly infringes the claim.

In order to prove contributory infringement, [patent holder] must prove that each of the above requirements is met. This proof of each requirement must be by a preponderance of the evidence, i.e., that it is more likely than not that each of the above requirements is met.
