Judging from the information provided by the landlord, it may be a bit reluctant to start with the technical scheme to explain that it has "outstanding substantive characteristics" compared with the existing technology.
However, there are several auxiliary criteria for the review of creativity in the Review Guide, that is, those who meet one of the following conditions can be considered creative and will not be reviewed for "outstanding substantive characteristics" and "significant progress".
The invention of (1) solved the technical problem that people have been eager to solve, but it has not been successful.
(2) The invention overcomes the technical prejudice.
(3) The invention has achieved unexpected technical effects.
(4) the commercial success of the invention (directly caused by the technical characteristics of the invention)
The landlord may wish to start from point (3) above and emphasize that your technical scheme has achieved unexpected technical effects (such as the yield is obviously higher than that in the existing technology, and the product quality has been significantly improved, etc.). , and achieved a qualitative leap, which is unpredictable by ordinary technicians in the field on the basis of the existing technology). Of course, these data reflecting the yield and product quality are best recorded in the original application documents. If it is not recorded in the original application documents, it shall reply to the examination opinions.
If the product has been put on the market for sale, you can also combine with point (4) to explain that due to the superiority of the technical scheme, the cost of your product has been reduced and the sales volume has increased. (need evidence to support), it has achieved great success in business.
If you can make a convincing statement to the examiner according to the actual situation of the case, I believe your patent application still has the prospect of authorization.
