712日,荣昌生物制药(烟台)有限公司在人民大会堂新闻发布厅公布了其自主研发生物新药RC18(通用名泰它西普,商品名泰爱)治疗系统性红斑狼疮(SLE)的关键II/III期临床研究的结果,显示泰它西普高剂量组治疗48周的SRI(系统性红斑狼疮应答指数)显著高于安慰剂对照组(79.2% vs 32.0%),而且安全性表现优异,病人耐受性良好。

 

系统性红斑狼疮

系统性红斑狼疮(SLE)是一种复杂的系统性自身免疫病、常常导致多器官、多系统损害,是危及生命的重大疾病,多发于15-45岁的生育年龄妇女,男女比例约为1:9。我国流行病学调查报告显示,系统性红斑狼疮患病率为70/10万人,中国大约有患者100万人,全球约有患者500万人。目前我国临床治疗缺乏有效的治疗手段,常规治疗多以糖皮质激素(泼尼松、氢化可的松、倍他米松)、免疫抑制剂(环磷酰胺)、抗疟药(羟氯喹)及生物制剂等为主,这些药物常常伴有较大的毒副反应,特别是临床常用的糖皮质激素长期使用对人体危害很大。

系统性红斑狼疮对新的治疗药物具有巨大的临床需求,但其新药研发异常困难,近年来国际上的III期项目基本都以失败告终。自1955年的羟氯喹以来,美国FDA在过去的60多年只批准过一个治疗系统性红斑狼疮新药上市,即2011年获批格兰素史克的贝利尤单抗(贝利木单抗),该药最近也在国内批准上市,但无论是价格上,还是治疗效果(长期用药、无法治愈)上都难以满足临床需求。

泰它西普详情

虽然系统性红斑狼疮的发病机制并没有完全阐明清晰,但是主流观点多认为这是一种B细胞过度增生导致的自身免疫性疾病,受遗传因素、环境因素、雌激素水平等各种因素相互作用的刺激,B细胞过度增生,产生大量的自身抗体,并与体内相应的自身抗原结合形成相应的免疫复合物,沉积在皮肤、关节、小血管、肾小球等部位,然后在补体的参与下,引起急慢性炎症及组织坏死。或者抗体直接与组织细胞抗原作用,引起细胞破坏,从而导致机体的多系统损害。

国内外多项研究表明,系统性红斑狼疮的形成与人体BLySAPRIL因子的异常增多直接相关,BLySAPRILB淋巴细胞分化成熟的关键因子,该因子的过度表达是系统性红斑狼疮等多种B淋巴细胞相关的自身免疫疾病的重要原因,抑制BLyS/APRIL能更加有效地降低机体免疫反应,达到治疗自身免疫疾病的目的。

由荣昌生物自主研发的生物Ⅰ类新药泰它西普,研究代号是RC18RCT-18,世界卫生组织(WHO)通用名Telitacicept,国家药典委员会通用名泰它西普,商品名泰爱,是同时结合BLySAPRIL的双靶向抗体融合蛋白药物,能高效阻断BLySAPRIL与其受体之间的相互作用,从而有效地阻断B淋巴细胞的分化成熟,抑制过度的免疫反应,用于治疗系统性红斑狼疮、类风湿性关节炎等多种自身免疫疾病。泰它西普于2011年从国家药监局获得首个临床试验批件,2012年在北京协和医院完成Ⅰ期临床试验,20137月,获国家食品药品监督管理总局Ⅱ、Ⅲ期临床试验批件。除了系统性红斑狼疮外,目前还有6个适应症正在或即将开展Ⅱ/Ⅲ期临床试验。

泰它西普vs 贝利木单抗

贝利木单抗所针对的靶点是BLyS,中文名B淋巴细胞刺激因子,因此也不难理解贝利木单抗的作用机制。通过特异性结合血清中的可溶性BLyS,贝利木单抗可以阻断BLySB细胞上的受体结合,抑制B细胞增殖以及B细胞向浆细胞的分化,从而减少血清中B细胞产生的自身抗体,达到治疗SLE的目的。

201112月发表于Arthritis Rheum杂志的一项全球、随机、安慰剂对照III期临床研究(NCT00410384)入组了819例患者,贝利木单抗的52SRI显著优于安慰剂组(43.2% vs 33.5%)。

20183月发表于Ann Rheum Dis杂志的一项中国、韩国、日本地区的随机、安慰剂对照III期研究(NCT01345253)入组了677例患者,贝利木单抗的52SRI显著优于安慰剂组(53.8% vs 40.1%)。

如果对比此次荣昌生物公布的临床数据可以发现,泰它西普相比安慰剂(79.2% vs 32.0%)对SRI的改善程度要明显好于60年来唯一的SLE新药贝利木单抗。这一临床结果,既是系统性红斑狼疮疾病领域的里程碑,也是中国创新药开发实力提升的又一个标志。

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.

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.
