355. Observations by third persons on patentability.

Where an application for a patent1 has been published2 but a patent has not been granted to the applicant, any other person may make observations in writing to the comptroller3 on the question whether the invention is a patentable invention, stating reasons for the observations; and the comptroller must duly consider the observations4.

The comptroller must send to the applicant a copy of any observations on patentability he receives5 except for those which, in the opinion of the comptroller, would disparage any person in a way likely to damage such person, or be generally expected to encourage offensive, immoral or
