1. The patent of the compound (usually a compound with similar structure * * * enjoys the same protection, which is a bad imitation).
2. Process patent (the best process route for synthesizing a compound or a class of compounds was useless in China before. Everyone wrote a fake process to bypass this route for declaration, but most of them still use this route in actual production. But in the future, it is required that the declaration process and the production process must be consistent, and I don't know what will happen)
Natural medicine:
Effective components, derivatives and effective parts in natural products (generally protected together with the extraction and purification process, efficacy, indications and synthetic route of derivatives).
Drugs:
1. Prescription patents (the most common and practical, including component patents)
2. Process patent (similar to pharmaceutical process patent, of little value)
3. Patent of dosage form (it is difficult, unless you can make a brand-new dosage form completely different from the existing dosage form, it is basically impossible to authorize)
Pharmacology:
Patent of experimental technology (sorry, intellectual property of pharmacology is unfamiliar, please add it)
In medicine:
Patents of analytical methods (usually specific varieties or chemical components, the improvement and improvement of existing analytical methods will have considerable economic significance if they can be included in national standards).
Patents on quality standards (not very common, unless the compound itself is brand new, or it is really a leap forward in the original standard level, it is unlikely to be granted).
Clinical medication:
Indication patent (it seems quite useful, in fact, I don't write this indication in the drug instructions. I recommend it to the doctor in clinic, provide relevant experimental data and information, and show him your patent for indications. Do you think he can use it? )
The above are some common patent types in pharmacy. My brother is just ignorant and has limited knowledge. I hope you can correct me and improve it.
