When Will the 1-Year Grace Period for Patents End?

Dear Rich: I filed a provisional patent application this week. I've been selling my product that I hope to patent for the past three months. The new patent law ends the one-year grace period. So where does that leave me and my application? You should be fine, provided that you file your regular patent application within a year of the provisional filing. The aspect of the law that you're referring to doesn't go into effect until March 16, 2013, and only applies to patents filed on or after that date.
What about the one-year grace period? The one-year grace period -- which allowed applicants to obtain patents even if if they had been selling or had published their patent less than a year before filing -- will terminate (with some exceptions) on March 15, 2013. As David Pressman, author of Patent It Yourself, recently explained in his excellent analysis of the America Invents Act:
"The one-year grace period has been decimated so that any publication, public use, or offer of sale of an invention before an application’s actual filing date will bar the application. An exception: if the actual inventor-applicant created the publication and it was made up to one year before the filing date, it will not bar the application. However it is still unwise for an inventor to publish before filing since they will lose their foreign filing rights and another person may see the publication and file their own application on it before the true inventor files, thus requiring an expensive and uncertain derivation proceeding."
