Q. Do you have to mark the patent number on the product packaging or website?

December 28, 2023

A: This is covered by Federal law 35 USC 287.

The law limits the patent holder's ability to recover for past patent infringement damages to the first point in time when the infringer was notified about the patent. By contrast, by marking the product, the infringer is legally assumed to have notice as of the time the patent holder first started marking the product.

So this can make a big difference in patent damages. Say an infringer had been infringing your patent for the last three years, but you had never marked your patent product with the patent number. Then you discover the problem and send the infringer a notification letter. The infringer only owes damages from the time of your letter, and not the previous three years. ... Read More

Q. Life sciences patent lawyer Q: can I patent modified protein production protocol never used for this protein but others

September 25, 2023

A: A lot will depend on whether your modified protocol is legally "obvious" or not. Here, the legal question is if the modification would appear apparent to a person of average skill in the art (here, "average skill" in biotech is Ph.D. level).

If you did something unusual or obtained unexpectedly good results, this would be an argument favoring non-obviousness. On the other hand, if the examiner can look at other prior-art protein production protocols and show that your modified method employs techniques that the examiner can find in these prior art methods, then this would be an argument against patentability.

Other arguments, such as opinions of experts in your field and possibly commercial success, may also be a factor. ... Read More
