哮喘又名支气管哮喘,是由众多细胞及细胞因子参与的气道慢性炎症性疾病,是一个全球性关注的慢性疾病。主要特点包括:症状反复、气流受阻、气道高反应和潜在的炎症反应;表现症状为:发作性咳嗽、胸闷及呼吸困难,多在夜间和(或)凌晨发生。

根据WHO统计,全世界有2.35亿人饱受哮喘的折磨。并且患者数量呈逐年递增趋势,尤其是儿童患者。该类疾病属于症状易反复的慢性疾病,需要长期用药,因此,治疗哮喘相应药物的研究与开发刻不容缓。

慢性阻塞性肺疾病(COPD)是一种以不完全可逆的气流受限为特征的慢性肺部疾病,临床上常表现为反复发作的咳嗽、咳痰、呼吸困难等症状,通常呈现出进行性进展的特点,包括了绝大部分慢性支气管炎和肺气肿。随着疾病发展,导致气道重构,最终发展为不可逆性气流阻塞,或与哮喘重叠共存发生。

COPD是全世界范围内发病率和死亡率最高的疾病之一。2015年,全球有320万人死于慢性阻塞性肺病,而患病率从1990年以来增长了14.7%。根据世界卫生组织调查的数据估计,COPD将在2030年成为全世界继心脏病、癌症之后的第三位主要死因。

国内的情况也并不乐观,根据钟南山院士主持的一项流行病学调查结果,目前中国COPD总体患病率为8.2%,其中男性患病率为12.4%,女性患病率为5.1%。COPD患者目前在中国已超过4000万,每年因为慢性阻塞性肺而死亡的人数超过100万。预计2003-2033年,中国将有6500万人死于COPD,而中国COPD的死亡率也跃居各国之首。

哮喘及COPD治疗药物的厂家集中在葛兰素史克(GSK)、阿斯利康和勃林格殷格翰3家,其中阿斯利康的信必可(Symbicort)专利即将到期,该药是一种复方药,用于哮喘和COPD的治疗,最初于2006年获批上市,2017年的销售额约为28亿美元。

信必可简介

名称:布地奈德/福莫特罗(budesonide/formoterol)

商品名:信必可(Symbicort®)

上市时间:2006年(FDA)

原研公司:阿斯利康(AstraZeneca)

主要适应症:哮喘和慢性阻塞性肺病(COPD)

剂型:粉末吸入剂

化学结构:

 

budesonide

 

formoterol

信必可的作用机制

信必可为复方制剂,由福莫特罗和布地奈德组成。其中福莫特罗为长效选择性β2受体激动剂,布地奈德为肾上腺素皮质激素。福莫特罗具有强力而持久的支气管扩张作用,呈剂量依赖关系,它能使第一秒用力呼气容积(FEV1)、用力肺活量(FVC)和呼气峰流速(PER)增加,并在吸人数分钟后可扩张支气管、减少气道阻力

 

原研专利情形

需要注意的是,阿斯利康已成功赢得了Symbicort的儿科独占权,从而将仿制药的竞争推迟至2019年5月。

吸入剂配合装置,仿制难度大

从剂型来看,肺部释放的粉雾吸入给药剂型主要是定量吸入气雾剂(MDI)、溶液雾化吸入剂、可溶性干粉吸入剂(DPI)三大类,这是该领域药品与其它治疗领域产品的最大区别,由于粉吸入剂仿制难度较大,预计专利到期之后,短时间内还不会对其市场产生较大影响。局部肺部给药,除了化合物的研究之外,还需要配合相关的给药装置,就这一点来说也给仿制带来一定的难度。

 

国内仿制情况

除了2010年以前申报的几家还在等待已经政策巨变且遥遥无期审评审批之外,2010年之后就没有该产品的仿制申报,而正大天晴申报的布地奈德福莫特罗粉吸入剂(胶囊型),则在2015年获得的审评结论是不批准,可见这个产品仿制的难度。目前该药仅从瑞典进口。

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.
