Intellectual Property Directions

Keeping your invention as a trade secret just got a lot less risky under the new patent laws – assuming, that is, that your invention is a process or apparatus that you use internally to  make a product or perform a service for a customer. On the other hand, if your secret is embedded in what you are selling – enterprise software sold/licensed under non-disclosure, for example – then you are probably still at risk of being sued for infringement should someone later patent your invention.

Let’s be clear about what the trade secret risk was, prior to September. Perhaps you had invented a manufacturing technique that allowed you to produce widgets significantly faster/better/cheaper than any other manufacturer. From the finished product, no one could reverse engineer your internal manufacturing technique. Typically you would try to keep the details of your technique as a trade secret instead of filing a patent application. Why? You kept it as a trade secret because your patent application, by definition, reveals your secret process and yet it is hard to enforce your patent since you would not be able to tell from your competitor’s finished products if they are infringing your patent.

The risk, however, is that a competitor who independently invented the same technique after you did was (and still is) free to patent it. And once his patent issued, you would be an infringer. Of course, it’s true that it’s hard for your competitor to enforce his patent rights against you, since your finished products don’t reveal your infringing activities. But nevertheless, you were put at risk of being sued for infringement even though you had invented the invention first and had been using it for perhaps many years.

But at last the new patent law has removed this Catch-22, at least in most cases. Under the new law, your prior commercial use of your invention will serve as a defense against an infringement suit. To make use of this defense , generally, you must be able to prove that you were using the invention “commercially” at least one year prior to the filing date of the patent application. Essentially you have to be using that great manufacturing technique to actually make and sell products.

Notice that these “prior user rights” only protect you from an infringement suit for using the invention. It does not allow you to sell copies of the invention to other manufacturers. But as of this past September, you can feel a little less paranoid about being on the losing end of an infringement suit for using your own trade secret invention. As always, it is a good idea to discuss your patent strategy with your patent attorney to understand how the details of the law affect your situation.
