We know that the establishment of patent and copyright protection is a time-consuming and laborious thing. Every country has its own set of intellectual property protection system, and it will take some time from the application for copyright protection to the result. The plagiarism of creativity in the game industry is often cross-border, and sometimes manufacturers have to have an office abroad if they want to protect their rights properly. As a kind of creativity and idea, playfulness can hardly be truly defined as a patent. The international patent standard is that your patented invention needs to have the ability of industrial application, and there are obvious innovative elements in the invention.
Take the game of eating chicken as an example. The survival tactical game of "transporting 100 people to a desert island full of weapons and hurting each other, leaving only the last one" was really popular in Survival of the Jedi, but is it really novel enough to apply for patent protection? There are not a few games that have similar ideas but are buried because of the times. Moreover, once the patent of this game is born, it will mean that no one can infringe and adapt this patent in the next 20 years.
So far, many people in the foreign industry have no good methods in this regard. Most experts in the field of law and games still suggest that if developers want to protect their creativity, they need to pay more attention to patents and copyrights, so as to "save the country by curve". Take the patented invention as an example, because the requirements of patented invention must be based on the real thing, if artistic style, program code, game creativity, gameplay, etc. want to be protected in the patent, efforts should be made from the design stage. Guitar Hero is a good example. It is considered as its music game and has applied for a patent. Like Guitar Hero, the use of physical guitar peripherals with rhythm games has successfully passed the patent examination, and the unique gameplay of Guitar Hero cannot be maliciously copied.
