依鲁替尼是经FDA突破性药物通道批准的第二个新药（第一个为obinutuzumab），同时还享有FDA的另外两项buff，以及上市后7年的行政保护。

依鲁替尼（ibrutinib）是Johnson Johnson公司和Pharmacyclics公司合作研发的靶向抗癌新药，于2013年11月13日获美国食品药品管理局（FDA）批准上市，商品名为Imbruvica,该药用于套细胞淋巴瘤（mantle cell lymphoma, MCL）的治疗。依鲁替尼的中文化学名称：1-[3(R)-[4-氨基-3-(4-苯氧苯基)-1H-吡唑并[3，4-d]嘧啶-1-基]哌啶-1-基]-2-丙烯-1-酮；英文化学名称：1-[3（R）-[4-amino-3-（4-phenoxyphenyl）-1H-pyrazolo [3，4-d] pyrimidin-1-yl] piperidin-1-yl]-2-propen-1-one;分子式：C25H24N6O2;分子量：440.50；CAS登记号：936563-96-1.

2013年11月13日，美国食品药品管理局（FDA）批准了Imbruvica(Ibrutinib-依鲁替尼)可用于套细胞淋巴瘤(MCL)的治疗。MCL是一种罕见的非霍奇金淋巴瘤，在美国所有非霍奇金淋巴瘤病例中大约占到6%。通常确诊为MCL时，癌细胞已扩散至淋巴结、骨髓和其它器官。

作用机理：依鲁替尼是一种小分子BTK抑制剂，能够与BTK活性中心的半胱氨酸残基共价结合，从而抑制其活性。BTK全称Bruton'styrosinekinase，在BCR 信号通路、细胞因子受体信号通路中传递信号，介导B细胞的迁移、趋化、粘附。临床前研究证明，依鲁替尼能够抑制恶性B细胞的增殖、生存。

临床试验：111例既往至少接受过一项治疗的患者经依鲁替尼治疗后，总应答率为65.8%（完全应答17.1%+部分应答48.6%），中位持续应答时间为17.5个月。

补充说明：由于多个加速buff的加成，该药的临床试验显得很简陋，入组患者只有111例，临床终点是应答率而不是生存期。套细胞淋巴瘤是一种罕见非霍奇金淋巴瘤，之前FDA分别于2006年、2013年批准硼替佐米、来那度胺治疗该症。依鲁替尼是Johnson&Johnson从Pharmacyclics高价买入的重点品种，除了治疗套细胞淋巴瘤外，还用于慢性淋巴细胞白血病、小淋巴细胞淋巴瘤。

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.

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.

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.
