The criteria for judging the practicality of patents are as follows:
First of all, a practical invention should be able to be manufactured or used, that is, it should be implementable.
To put an invention into practice, there must be a concrete plan. An invention with only one idea and no concrete embodiment is called an unfinished invention. Unfinished inventions are impractical, so they are not practical.
If a scheme itself violates the laws of nature, then no matter how clever the invention is, it is definitely not practical. Because inventions that violate the laws of nature are impossible to implement.
Another meaning of enforceability is to require an invention to be repeated. Although some schemes are detailed and specific, they cannot be implemented repeatedly in industry, and they are also not feasible.
Second, practical inventions must be able to bring positive effects, that is, beneficial.
Beneficial here means that an invention can play a positive role in social and economic development and the construction of material civilization and spiritual civilization. Usually, this positive effect can be manifested in improving product quality. Improve the working and production environment, save energy, reduce environmental pollution and reduce production costs.
Characteristics of patent practicality:
Practicality: the invention or utility model must be manufactured in industry, or the method of the invention can be used in industry. If the creative achievement is only theoretical, you can't apply for a patent.
Repeatability: The theme of an application for a patent for a practical invention or utility model should be repeatable.
Beneficial: Practical inventions and utility models should have positive effects. This comes from the social attribute of the invention, which requires it to provide positive and beneficial effects in future practical implementation. Positive benefits are usually manifested in improving product quality, increasing product output, saving raw materials, reducing costs, improving labor productivity, improving working conditions and preventing environmental pollution.
