抑郁症是一种常见的精神疾病，全球有超过3亿人患有抑郁症，分布于各个年龄层，最严重时，抑郁症可引致自杀，每年有近80万人因自杀死亡。来自中科院昆明植物研究所的消息称，该所研究人员通过对传统中药厚朴的研究，找到了作用于褪黑素受体的具有抗抑郁功效的新型小分子，可用于新型抗抑郁药物的研发。

此前，中国科学院昆明植物研究所陈纪军研究团队利用本研究组建立的抗精神疾病细胞和整体动物研究平台，对赤芍、柴胡、酸枣仁、合欢花、远志等传统中药进行了研究，发现了系列活性化合物。

褪黑素(N-乙酰基-5-甲氧基色胺，Melatonin)主要是由人体松果体产生的一种胺类激素，褪黑素受体主要由MT1，MT2和MT3三个亚型组成，褪黑素的调节作用通过与不同受体结合而产生不同的生理反应。褪黑素与MT1受体结合，可以降低cAMP的生成和抑制PKA的活性，从而调节生物钟；MT2受体的主要作用可能为同步作用和血管舒张作用。此外，褪黑素还具有抗氧化作用，催眠作用，免疫调节作用以及调节人的情绪和行为等作用。褪黑素生成减少或者褪黑素受体表达降低是导致乳腺癌的主要因素之一，同时也会引发一系列神经退行性疾病如帕金森症，阿尔兹海默病以及慢性失眠和抑郁症。利用褪黑素受体的体外筛选模型，研究人员从厚朴(Magnolia officinalis Rehder et Wilson)中发现厚朴酚对受体具有一定的激动作用，为了发现高活性的化合物，他们对厚朴酚进行结构修饰与优化，合成系列衍生物，通过体外活性测定，他们发现厚朴酚葡萄糖苷（7c）活性最强，较厚朴酚对褪黑素受体的激动作用增强2.5至7.5倍，同时，体内药效评价结果也表明，化合物7c可通过影响小鼠脑内神经递质水平，发挥潜在抗抑郁作用。

随后对化合物7c进行了体内代谢产物研究和初步安全性评价，从小鼠血浆、尿液和粪便中共检测到25个代谢产物，急性毒性实验表明该化合物具有较好的安全性，具有开发成新型抗抑郁药物的潜在应用前景。

这项成果已在学科领域顶尖刊物《欧洲药物化学杂志》上发表，并于今年初申请了“厚朴酚糖苷在制备治疗中枢神经系统疾病药物中的应用”中国专利，其主要权利要求为“化合物厚朴酚‑4‑O‑β‑D‑葡萄吡喃糖苷(见下图结构式)或其药用盐在制备褪黑素受体激动剂中的应用”，目前已进入实审阶段。

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. 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.
