化合物结构最终以盐型状态上市,往往可以改善药物游离状态下部分理化性质数据,这也是大多数创新药物研发工作的一部分,但在已发表的化合物的基础上,仅仅通过更改盐型即得到一个I类新药,并已发展到国内NDA阶段,这样的例子实在不多见,毕竟原研公司遗漏一个更优的盐型是不太可能的。然而就是这样的极小概率事件,恒瑞抓住了,这个产品就是当前处于NDA阶段并获得国内优先审评资格的甲苯磺酸瑞马唑仑。

甲苯磺酸瑞马唑仑简介

 

瑞马唑仑是由德国Paion公司开发的一种短效GABAa受体激动剂,是苯二氮卓类中枢神经系统药物。甲苯磺酸瑞马唑仑则是江苏恒瑞研发的瑞马唑仑成盐化合物,相比瑞马唑仑具有更高的稳定性,目前已经在中国提交上市申请,用于患者的静脉麻醉、镜检时镇痛、术前麻醉和ICU镇静。

   同靶点药物现况

 

甲苯磺酸瑞马唑仑同靶点上市药物已达到74个,NDA申请状态3个,临床III期品种11个,临床II期品种15个,临床I期品种27个,撤市药物4个(分别为复方盐酸阿米替林/氯氮䓬、丁巴比妥、阿吡坦、甲喹酮)。临床状态方面,处于进行中的24项,无进展10项,终止28项。

 

中国I类新药方面,研发最为靠前的即为江苏恒瑞的甲苯磺酸瑞马唑仑。紧随其后的III期临床产品分别为Paion Pharma/宜昌人福药业的苯磺酸瑞马唑仑、海思科的HSK-3486;II期临床产品为D-Pharm/江苏恩华药业DP-VPA;I期临床产品分别为苏州沪云的SPT-07A 、苏州旺山旺水生物医药/中国科学院上海药物研究所/上海特化医药科技的TPN102

   甲苯磺酸瑞马唑仑在中国的进程

2012年6月,食药监总局承办恒瑞递交的1类新药临床申请(IND)。

2013年4月,甲苯磺酸瑞马唑仑获得中国化药1.1类临床批件。

2013年10月,甲苯磺酸瑞马唑仑临床I期研究启动。

2017年5月,甲苯磺酸瑞马唑仑获CFDA批准,进入Ⅲ期临床。

2018年3月,甲苯磺酸瑞马唑仑在中国申报生产。

2018年4月,据总局《关于鼓励药品创新实行优先审评审批的意见》(食药监药化管〔2017〕126号),CDE组织专家对申请优先审评的药品注册申请进行了审核论证,江苏恒瑞的甲苯磺酸瑞马唑仑入选理由为“与现有治疗手段相比具有明显治疗优势”。

   药理、临床信息情况

 

江苏恒瑞对于产品甲苯磺酸瑞马唑仑的信息披露相对不多,其临床适应症主要针对胃镜、结肠镜的镇静麻醉,而从原研瑞马唑仑的相关报道中可知,瑞马唑仑是结合了咪达唑仑的安全性与异丙酚(丙泊酚)的有效性,但游离碱稳定性较差,成药性不高,而江苏恒瑞在瑞马唑仑的基础上,使用甲苯磺酸盐,而非原研公司的苯磺酸盐,毒性相对降低,故相对而言,临床安全性更高

   总结

 

从长远的角度来看,甲苯磺酸瑞马唑仑的上市将成为恒瑞医药新的业绩增长引擎,开拓恒瑞在静脉全身麻醉领域的战略性布局,带动在研产品管线中储备药物的成长,结合恒瑞在吸入性麻醉药物领域的优势,整合静脉/吸入麻醉的整个产品管线,这是一款具有开拓性意义的药物。尽管如此,甲苯磺酸瑞马唑仑这样一个没有化合物专利的“新药”,仅仅凭借盐型专利作为第一道防线,强仿似乎不难,当然,也有可能是因为拥有着强大的销售能力以及麻醉市场占比状态,恒瑞并不担心产品的未来走势以及对手的竞争,接下来能否获批以及未来之路如何,值得大家持续关注。

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.
