why patent is required?

Patents are required for several reasons:

1. Legal protection: Patents provide legal protection for inventors and companies by granting them exclusive rights to their inventions. This means that others cannot make, use, sell, or import the invention without permission. If someone does infringe on a patent, the patent holder can take legal action to stop them and seek damages.
2. Incentive for innovation: Patents serve as an incentive for inventors and companies to invest time, money, and effort into developing new and useful products, processes, and technologies. By providing exclusive rights to their inventions for a certain period of time, typically 20 years, inventors are encouraged to bring their ideas to market and make them available to the public.
3. Promotion of progress: Patents promote progress in science and technology by encouraging inventors to develop new and useful innovations that can benefit society as a whole. By providing legal protection and exclusive rights, inventors are more likely to invest in research and development, which can lead to important discoveries and advancements.
4. Economic benefits: Patents can provide significant economic benefits to inventors and companies. By protecting their intellectual property, they can prevent others from copying their ideas and enter the market with similar products or technologies. This can help create a competitive advantage and lead to increased profits.

Overall, patents are required because they provide legal protection, serve as an incentive for innovation, promote progress in science and technology, and provide economic benefits to inventors and companies.
