Electronic Arts pledges free use for five accessibility patents

Electronic Arts pledges free use for five accessibility patents Recently, Electronic Arts (EA) announced a patent pledge that gives other companies and developers free access to five of its current accessibility-related patents and technology. The company promised not to enforce against any party for infringing any of the listed patents. Instead, EA hopes to encourage “innovation” and build new features that make video games more inclusive on a much larger scale by opening up the patents.  Electronic Arts (EA) is an American video game company founded in 1982. The company owns many popular and famous games, such as The Sims, SimCity, Apex Legends, Madden NFL and FIFA. Each of the games has more than 30 or 50 million sales volume. Significantly, esports involves FIFA and Apex Legends into the event list. Apex Legends has up to 1 billion players, and it is so popular that it has a Switch version. Within the freely available patents, one of which grabs everyone’s attention -- Apex Legends’ ping system (patent No. US 11097189). The ping system in Apex Legends, which excellently allows players to make communication and teamwork quick and easy without hearing or speaking, has been praised both as an impressive alternative to voice chat and as a great accessibility feature for players with a variety of disabilities.  The other patents include the technology widely used in the FIFA and Madden NFL. The innovations can automatically detect and modify colors (patent No. US 10118097 and CN 107694092) and contrast ratios (patent No. US 10878540) to improve gamers’ visibility with colorblindness and low vision. Furthermore, one of the patents relates to personalized sound technology, helping players with hearing issues by modifying or creating music based on their preferences (patent No. US 10790919).   The code of the mentioned technology is published on EA’s GitHub, and it is open to all developers. Thus, the developers can use it or adapt it for their games without spending the costs to research. It is good that EA shares the patents for free use and aims to create an accessibility-increased gaming environment for players. However, it is not “unconditional” to use the listed patents. In the pledge, EA mentioned that it may terminate the promise for a specific party which files a patent infringement lawsuit or other patent proceedings against EA. We can see parts of EV’s ambition behind the announcement—to build a large game developer league and a community of shared interests.     Reference: https://www.ea.com/commitments/positive-play/accessibility-patent-pledge https://iknow.stpi.narl.org.tw/Post/Read.aspx?PostID=14562 https://www.polygon.com/22639469/apex-legends-electronic-arts-patent-pledge-accessibility-developers https://www.theverge.com/2021/8/24/22638535/ea-accessibility-patent-pledge-apex-legends-ping-system https://www.gamesradar.com/ea-secures-a-patent-for-the-apex-legends-ping-system-and-its-giving-it-away-for-free/ https://dotesports.com/apex-legends/news/apex-legends-ping-system-is-now-patent-free-for-accessibility https://www.nintendolife.com/news/2021/08/apex_legends_ping_system_now_patent-free_as_ea_announces_accessibility_pledge Recently, Electronic Arts (EA) announced a patent pledge that gives other companies and developers free access to five of its current accessibility-related patents and technology.

The director of Nanjing Intellectual Property Protection Center, Mou Xiaojian, delivered a speech. Director Mu expressed his warm congratulations on the holding of this event and introduced in detail the new pattern of intellectual property protection in Nanjing. He said: At present, Nanjing has implemented a rights protection assistance network in the municipal area. With full coverage, Nanjing Intellectual Property Protection Center is willing to closely communicate and interact with Nanjing's innovation entities, and provide relevant public welfare services such as rapid pre-review, rapid rights protection, and comprehensive utilization for enterprises in need. In addition, Huang Funan, CEO of Gene Online, was unable to come to congratulate due to the epidemic, and recorded a congratulatory video.

Types of patents that are easily overlooked- Design Patent

Types of patents that are easily overlooked- Design Patent In recent years, as the public’s awareness of intellectual property has increased, people have begun to consciously use the patent law to protect their intellectual property rights. However, in the process of implementation, they often only focus on invention patent and utility model patent, and tend to ignore the protection of design patent. Recently, Midea sued Haotaitai for two models of CXW-300-D998 and CXW-300-D908 Haotaitai brand range hoods In the case of suspected infringement of its design patent (patent number: ZL201930621598.X), the Guangzhou Intellectual Property Court made a first-instance judgment after hearing that it determined that the two products of Haotaitai constituted infringement, and ordered it to immediately stop the infringement and compensate Midea, The company's economic losses and reasonable expenses totaled 360,000 yuan. In fact, appearance infringement cases have occurred from time to time before, such as: "Molly" blind box design patent case, "Siemens" switch design patent infringement dispute case received a compensation of 6 million yuan, three Casio watch design patents were infringed Received a compensation of 8.8 million yuan and so on. The reason why people ignore the protection of design patents, in the final analysis, is that they have insufficient knowledge of design patents. Today, let's take a look at what is protected by design patents and what rights protections can we apply for? Design patent definition: Article 2 of the "Patent Law", design patent, refers to a new design that is aesthetically pleasing and suitable for industrial applications based on the shape, pattern, or combination of products, and the combination of color, shape, and pattern. Protected range: The shape of the product; the pattern of the product; the shape and pattern of the product; the shape and color of the product; the pattern and color of the product; the shape, pattern and color of the product. Protection period: The term of protection for design patent rights is 15 years, calculated from the date of filing. What are the conditions for applying for a design patent? The design should be aesthetically pleasing Appearance patents should be suitable for industrial applications The design patent application should be novel The design patent application should be inventiveness What are the advantages and functions of design patents? Protect the rights and interests of enterprises in product designs and fight against infringements in market competition. To enhance brand value, the quality and quantity of patents are the embodiment of the company's innovation ability and core competitiveness. Receive consumer recognition. If a company's new product appearance is filed for a patent in a timely manner, its appearance design will enjoy the exclusive right. Nowadays, consumers often choose products with trendy and beautiful appearance when buying their products. Applying for a design patent is a necessary condition for applying for a high-tech enterprise.

Colopl Settles Patent Infringement Lawsuit with Nintendo by Paying $30 Million

Colopl Settles Patent Infringement Lawsuit with Nintendo by Paying $30 Million   This August, Nintendo and a game developer Colopl announced that they have settled for patent infringement regarding White Cat Project (Shironeko Project in Japanese), a smartphone game developed by Colopl. Although both companies did not publicly share exact details of the settlement, at least it is sure that Colopl agreed to pay 3.3 billion yen (about US$30.2 million) as the settlement fee for the proceedings, including the future license of Nintendo's patents.    How did the battle begin?  Being developed and published by a Japanese game developer, Colopl, White Cat Project is a free-to-play action role-playing game for Android and iOS systems. The mobile game was launched in July 2014 as well as got a television anime adaptation in 2020. It is incredibly popular to have more than 50 million downloads. Furthermore, the game is set to receive a Switch version titled "Shironeko New Project".    In September 2016, Nintendo noted the Colopl's game and considered that the game had infringed on several of Nintendo's technology patents. The two companies communicated with each other for over a year; however, Nintendo did not accept the explanations from Colopl, and Nintendo filed a lawsuit against Colopl at the beginning of 2018.    Nintendo claimed that Colopl infringed 6 of its patents. These patents protect touch-screen joystick functionality (patent no. JP3734820), multiplayer connectivity (patent no. JP5595991, JP6271692), confirmation screens in sleep mode (patent no. JP4010533), character attacks based on touch input locations (patent no. JP4262217), and a shadow effect placed on characters hidden behind the game geometry (patent no. JP3637031).   These patents almost cover various ways of game technology, especially the patent  JP5595991 and JP6271692. Their patent family is wide-reaching, and many divisional applications of the family are pending in Japan. They protect a communication game system and its related devices. It is not easy to detect the patent's existence and boundary since this kind of hardcore technique is so common in the gaming field and our daily lives.     The five-year patent war has been settled.  After a five-year dispute, the situation appeared to turn in Nintendo's favor as the Switch maker increased its monetary demands, which convinced Colopl to strike a deal that lets it use the disputed patents. Furthermore, a Switch version of White Cat Project remains in the works at Colopl.    With the extraordinary losses of Colopl, the legal battle between the two companies came to an end.
