Since he brought up that, "public use" or making the information "Known". The part that was new to me was that the "one year grace period" apparently no longer exists! So, according to him, it was implied that if were working out of open-floorplan co-working ideas that we're pushing, you would have essentially contributed you inventions to the public domain and couldn't file a patent on it (since the 1 year grace period no longer exists).
This information struck me as an important thing that anyone working in a shared workspace should know & that perhaps have already worked out. Hence, reaching out to HN.
Here's the info of the lawyer who did the presentation: http://www.hctlaw.com/pages/professionals/stephen-c-thomas-e...
