Arcade game manufacturers employ multiple strategies to protect their intellectual property (IP) from knockoffs, ensuring their creative and financial investments remain secure. One of the primary methods is obtaining legal protections such as copyrights, trademarks, and patents. Copyrights safeguard game designs, software code, and artwork, while trademarks protect brand names, logos, and slogans. Patents may cover unique hardware mechanisms or gameplay innovations.

Additionally, manufacturers often embed digital security measures, such as encryption and licensing agreements, to prevent unauthorized duplication. Some companies also use hardware-specific locks or proprietary components that are difficult to replicate.

Legal action is another critical tool—manufacturers actively monitor the market for counterfeit products and pursue litigation against infringers. Collaborating with international customs agencies helps intercept knockoff shipments before they reach consumers.

Finally, fostering strong brand loyalty through high-quality gameplay and customer engagement discourages players from supporting counterfeit versions. By combining legal, technical, and marketing strategies, arcade game manufacturers effectively defend their IP from knockoffs.
