The specific signature scheme can be formulated according to the actual situation. Here are some possible solutions:
1. Sorting by degree of contribution: According to the degree of contribution of each person to the patent, the signatures are arranged in descending order.
2. Rank by position: rank by positions within the company, and rank signatures from high to low.
3. Sort by surname initials: sort by surname initials, and arrange signatures from front to back.
4. Sort by application time: sort by patent application time, and arrange signatures from the first to the last.
No matter which scheme is adopted, fairness and justice should be ensured and unnecessary disputes and contradictions should be avoided. At the same time, we must also abide by relevant laws and regulations and company regulations to ensure legal compliance.
