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
