At #5 is “Waiting to consider international intellectual property protection.” In fact, the example given by Prof. Bagley relates to waiting to consider IP protection per se, pointing out that in the US, “if an invention is sold or made public, there's a year's grace period to file a patent application. Everywhere else, if the invention is sold or publicized prior to filing the patent application, the invention is unpatentable in that country.”
At #4 is “Disclosing inventions without a non-disclosure agreement.” “Is it wise to get potential venture capitalists to sign a nondisclosure agreement?” she asks, suggesting that “In the best of all worlds, yes, but most won't. Before disclosing to anyone, one must learn who has a reputation for integrity in the industry.”
And at #3 comes “Starting a business while employed by a potential competitor, or hiring employees without first checking their agreements with the current employer and their knowledge of trade secrets.”
But top of Prof. Bagley's list comes “Thinking any legal problems can be solved later”. “Many of the points made here are problems that can't just be patched up later” she explains.
