The Portland Retro Gaming Expo recently hosted its largest event celebrating classic video and arcade games that have shaped popular culture. This year’s expo featured panels with iconic innovators such as Nolan Bushnell (Atari), Ted and Carrie Tahquechi, Jeff Minter (Tempest 2000), and Daniel and Carlose Pesina (Mortal Kombat) highlighting the industry’s rich history.
Since the 1970s, the video game industry has evolved dramatically—from simple pixelated games to immersive modern experiences. This growth was fueled by creative innovations, many of which were protected through patents. The first notable patent was Ralph Baer’s “interactive television gaming system,” which led to the Magnavox Odyssey, the first home console. This marked the beginning of companies using patents to secure competitive advantages, particularly as the industry matured during the “Golden Age” of arcade games and home consoles in the late 1970s and 1980s.
Initially, patents covered physical hardware like controllers and cartridges. However, companies began protecting gameplay mechanics, such as Namco’s 1994 patent for the “loading screen mini-game” US Patent 5,718,632 which prevented competitors from using similar features until the patent expiration in 2015.
Patents have also played an essential role in preserving gaming history. When companies file patents, they are required to provide detailed descriptions of their inventions, which often serve as valuable documentation of technological developments in the gaming industry. Today, retro gaming continues to thrive, with many older patents having expired, allowing fans and hobbyists more freedom to recreate and distribute classic games. However, trademarks and copyrights still provide some protection for the innovators.
As the games industry has continued to evolve, and more recently with the rise of virtual reality, augmented reality, and artificial intelligence, the role of patents will likely grow more complex. Companies will continue to secure patents on cutting-edge technology to maintain competitive advantages.
The patent system has played a critical role in shaping the games industry, providing companies with the tools to protect their inventions and push technological boundaries. The history of retro gaming patents remains a testament to the technological creativity and legal ingenuity that have defined the industry for decades.
