为什么现在推出功率SiC专利监测服务？

去年的分析指出，全球 SiC 功率元件的智慧财产权 (IP) 竞争加剧。同时，许多历史悠久的智慧财产权公司和智慧财产权领导者以前专注于在特定地区保护其发明，现在正在新的地区（特别是欧洲和中国）申请专利。随着电动车 (EV) 推动新兴电力碳化硅市场的发展，各公司正相应调整其智慧财产权策略。其他以前较少参与专利活动的大公司现在也开始保护与碳化硅功率装置相关的新发明。考虑到建立强大的 SiC 供应链所需的投资水平，专利可以成为早期 SiC 公司在新竞争对手进入市场时确保市场占有率的重要槓桿。

此外，自2015年以来，中国研究机构和企业的发明活动逐渐增加。2023年，中国企业将产生超过70%的功率SiC专利出版品。2022 年，KnowMade 发布了基于中国企业在整个 SiC 供应链中的专利活动对新兴中国 SiC 生态系统的分析。儘管此类专利的品质可能会受到质疑，但这种情况对寻求在中国发展製造和业务的半导体市场全球竞争对手提出了新的课题。

2021年，功率SiC市场的两家早期领先公司因利用与平面MOSFET技术相关的两项基础专利以及潜在的智慧财产权使用费而被美国学术组织提起诉讼。由于自 2022 年以来，大多数 SiC 功率元件领域的主要公司在授予的专利方面都显着提高了其智慧财产权地位，预计未来几年 SiC 公司之间的诉讼案件可能会增加。IP活动的加速对于沟槽MOSFET技术来说是一个更敏感的问题，这可能成为功率SiC市场的主要方向之一。然而，MOSFET 已成为一个非常繁琐的 IP 空间，使得新进入者很难保护新的闸极沟槽设计。

重要的是，一些公司在功率碳化硅市场缺乏雄心勃勃的智慧财产权策略。这种情况表明，重大举措（智慧财产权/製造合作伙伴关係、併购等）将进一步重塑 SiC 专利格局。

在此背景下，监控主要公司的专利活动和智慧财产权策略极为重要。这些知识可以帮助您瞭解竞争对手的研发路线图和策略、评估风险并发现商机。SiC 的专利监控服务利用每季更新一次的 Excel 资料库，让您能够从季度分析报告以及与分析师的直接互动中受益。

Why implementing a power SiC patent monitoring service now?

In the Silicon Carbide (SiC) IP landscape 2022, KnowMade pointed out that the global intellectual property (IP) competition for SiC power devices was on the rise. On the one hand, many well-established IP players and IP leaders, who used to focus on certain regions to protect their inventions, were now patenting their inventions in additional geographical areas, especially in Europe and China. As electric vehicles (EV) were driving the emerging power SiC market, companies had been adapting their IP strategies accordingly. On the other hand, notable market players that hadn't been significantly involved in the patenting activity, started protecting new inventions related to SiC power devices. Considering the level of investments that has been required to establish a robust SiC supply chain, patents may be an important tool for early SiC companies to secure their market share as new competitors enter the market.

Furthermore, Chinese research organizations and companies have progressively ramped up their inventive activity since 2015. In 2023, Chinese players have produced more than 70% of all power SiC patent publications. In 2022, KnowMade released an analysis of the emerging Chinese SiC ecosystem based on the patenting activities of Chinese players across the SiC supply chain. Even though the quality of such patents may be questioned, this situation brings about new challenges for global competitors in the semiconductor market looking to develop their manufacturing and business activities in China.

In 2021, two of the main early players in the power SiC market were sued by a US academic player, leveraging two fundamental patents related to planar MOSFET technology, to seek damages and get potential royalties from their IP. In the next few years, more litigation cases are expected between SiC players, as most of the main players in the SiC power device landscape have significantly improved their IP position since 2022, in terms of granted patents. The acceleration of IP activities is even more sensitive for trench MOSFET technology, which may become one of the main directions for the power SiC market. Yet it has become a very busy IP space, making it difficult for challengers to protect new gate trench designs.

Importantly, several players apparently lack an IP strategy consistent with their ambitions in the power SiC market. This situation suggests that important moves (IP/manufacturing partnerships, M&A, ...) are yet to come, further reshaping the SiC patent landscape.

In this context, it is crucial to monitor patent activity and IP strategies of key players. Such knowledge can assist in understanding your competitors' R&D roadmap and strategies, evaluate the risks, and detect business opportunities. The SiC patent monitoring service allows you to take advantage of a quarterly-updated Excel database and benefit from both quarterly analysis reports and direct interaction with our analysts.

Benefits of the patent monitoring service

Keep a watch on your competitors' IP activities and their future intentions.

With the help of the patent monitoring service, you will be aware of your competitors' current patenting activities, their IP dynamics, patent transfers including acquisitions and licenses, patent litigation, technology development and R&D strategies. You will also be able to early detect new entrants in your business area.

Keep track of the latest technology developments and be ahead of technology trends.

By keeping note of any recent patent filings, you can track the newest innovations in the field. You will get details on claimed inventions and you can follow technology developments. New technical solutions could inspire and improve your R&D activity.

Prevent registration of IP rights that may be harmful to your business.

You will obtain information on patent applications filed even before exclusive rights have been granted and you can react in time to prevent registration of IP rights that may be harmful to your business.

React in time to infringements and mitigate legal risks.

Monitoring newly-issued patents allows you to regularly assess your freedom-to-operate, ensuring your products or processes are not covered by patents, and thus that they can be manufactured, sold or used safely without infringing valid IP rights owned by others.

Take advantage of free technologies and decrease R&D project risks.

By tracking both expired patents and abandoned patents, you will be able to identify inventions entering the public domain that you can use safely for your development.

Understand the current IP trends and IP strategy of competitors

On a quarterly basis, the report will provide the IP trends over the three last months, with a close look to key IP players and key patented technologies. Main patent applicants and their inventions, blocking patents, promising patents and key patents newly expired or abandoned will be highlighted.

Access to the IP analyst
