I'm an entrepreneur and inventor. I want to make a record here that I have no fucking idea whether publishing my invention is enough to have Prior Art, or whether I need to state the use of the invention in my business case, or whether I need to file a patent.
As an entrepreneur, an "inventor", and a patentholder: I believe this is simple:
(a) if you're planning on staking a claim on a patent, get a patent lawyer (no part of this bill reduces the need for IP lawyers; whether you like the concept of requiring IP lawyers or not is besides the point).
(b) if you're not planning on getting a patent (and I think you shouldn't, for simple pragmatic reasons), just publish what you're doing as soon as you can, and you'll have established a prior art track record.
The reform we're talking about changes the mechanics of competing claims for a patent, but it doesn't make prior art harder to establish (my understanding is that in a variety of little ways it makes prior art easier to establish).
