Mr. A invented a new coffee machine that could also be a juice maker in 2010. This coffee machine was registered for patent on 31 January 2010 in Thailand, as it was a new, inventive, and industrial applicable product. Mr. A named this coffee machine as “Coffee and Juice” as its trademark and started selling it in the market without registering for trademark. It appears that “Coffee and Juice” is a major success. It has become a widely known product and very popular in Thailand.
Please answer the following questions;
a) How long does the patent protection of Mr. A’s “Coffee and Juice” last?
b) Can Mr. A use “Coffee and Juice” as trademark for his product?
