伴随着标准必要专利对市场竞争影响的日益加深,FRAND原则、竞争法以及不断衍化的司法判例对标准必要专利的实施产生了一定的限制。然而,在标准必要专利具体实施过程中,标准专利权人和标准实施者基于趋利避害使然,通过利用规则漏洞,分别实施“专利劫持”和“专利反向劫持”。在标准必要专利案件案件审理中,法院需综合考虑标准普适与专利垄断、专利维权与专利滥诉、诉讼自由与诉权滥用、竞争政策与产业政策等多方面因素,彰显司法衡平艺术,既要防止权利滥用,亦要避免“权利滥用被滥用”。

Code dissemination is one of the important services of wireless sensor networks (WSNs). Securing the process of code dissemination is essential in some certain WSNs applications, state-of-the-art secure code dissemination protocols for WSNs aim for the efficient source authentication and integrity verification of code image, however, due to the resource constrains of WSNs and the epidemic behavior of the code dissemination system, existing secure code dissemination protocols are vulnerable to Denial of Service (DoS) attacks when sensor nodes can be compromised (insider DoS attacks). In this paper, we identify five different basic types of DoS attacks exploiting the epidemic propagation strategies used by Deluge. They are (1) Higher-version Advertisement attack, (2) False Request attack, (3) Larger-numbered Page attack, (4) Lower-version Adv attack, and (5) Same-version Adv attack. Simulation shows these susceptibilities caused by above insider DoS attacks. Some simple models are also proposed which promote understanding the problem of insider DoS attacks and attempt to quantify the severity of these attacks in the course of code dissemination in WSNs.

2022年8月9日,美国总统拜登正式签署《2022年芯片法》并开始实施。作为对《2021财年国防授权法案》中芯片激励措施部分的进一步落实,该法共设置了7款规定,大致可以分为产业政策与“毒丸条款”两个部分:前者试图通过巨额财政援助补贴芯片制造企业来重建美国本土的芯片产业链,后者意欲拉拢全球的芯片企业赴美投资,阻遏中国及“其他受关注的国家”在先进芯片技术方面的发展势头。虽然《2022年芯片法》因为种种原因可能无法实现预期目标,但其的确对中国芯片产业发展的外部环境造成不利的影响。为此,中国应当从外交、产业以及知识产权3方面入手,积极应对,为中国芯片产业的突围开辟局面。
