Ms. Liu Jing is an agent of the Patent Litigation Department at CCPIT Patent and Trademark Law Office, primarily responsible for patent infringement litigation, patent invalidation, administrative litigation, patent search, and consulting services.
Ms. Liu Jing has worked at the Patent Office of the China National Intellectual Property Administration (CNIPA) for 16 years, including 6 years of experience in the Reexamination and Invalidation Board. During this period, she examined a large number of invalidation cases and accumulated rich experience in invalidation litigation.
(1)From 2023 to 2025, represented a well-known domestic semiconductor display device manufacturing enterprise in responding to a patent invalidation case filed by a renowned foreign enterprise. The case resulted in a complete victory: the petitioner ultimately withdrew the invalidation request, the patent right was stably maintained, and a settlement was facilitated between the parties.
(2)In 2025, represented a globally renowned Finnish consumer goods group in a utility model patent invalidation case, securing a victory with all patent rights declared invalid.
(3)In 2025, represented a globally leading Swiss MEMS sensor enterprise in a utility model patent invalidation case, securing a victory with both patent rights maintained as valid.
(4)From 2024 to 2025, represented a Belgian equipment manufacturer in an invention patent infringement case, securing a victory and facilitating a settlement between the parties.
(5)From 2024 to 2025, represented a German supplier of commercial vehicle braking systems and safety technologies in an invention patent invalidation and administrative litigation case, securing a victory with all patent rights declared invalid and the invalidation decision upheld. The first-instance administrative litigation of this case was listed as a public hearing case by the Beijing Intellectual Property Court. Through meticulous preparation and professional courtroom performance, we ultimately won the court’s support and obtained a favorable judgment.
(6)From 2022 to 2025, represented a well-known enterprise in Italy’s transportation engineering industry in an invention patent infringement litigation case. The case went through two trials of infringement litigation, on-site inspection, two trials of administrative litigation, and multiple invalidations. Relying on comprehensive and solid evidence collection, rich case-handling experience, and strong technical capabilities, we successfully overturned the original judgment in the second instance, ultimately winning the case for the client and securing punitive damages amounting to one to two times the economic losses.
(7)From 2022 to 2025, represented a renowned Swiss watch manufacturer in dozens of watch series design invalidation cases, all of which were won.
(8)From 2019 to 2025, represented a well-known U.S. welding equipment manufacturer in an invention patent infringement case, multiple invalidation and administrative litigation cases, ultimately achieving a complete victory and facilitating a settlement between the parties.
(9)From 2023 to 2024, represented a well-known domestic internet enterprise in an invention patent invalidation case. The client’s key products faced the significant risk of being removed from major e-commerce platforms, which would have seriously impacted their market share and commercial interests. Despite the difficulty of invalidation, a complete victory was ultimately achieved: all patent rights were declared invalid, the invalidation decision was upheld in two trials of administrative litigation, resolving the infringement risks and safeguarding the client’s commercial interests and market position.
(10)From 2020 to 2023, represented a domestic medical device manufacturer in an invention patent infringement case, invalidation, and administrative litigation. After the client lost the first instance of the alleged infringement lawsuit and the first invalidation request failed, our team accepted the engagement, successfully invalidated all involved patent rights, and timely applied to the Supreme People’s Court for retrial. As the infringement judgment had already taken effect, the executed judgment of patent infringement could not apply the procedure for reversal of enforcement in civil proceedings under the Patent Law. To prevent the actual enforcement of the client’s funds, our team submitted written opinions to the court and closely followed up on the enforcement process. Ultimately, although the patentee had applied for compulsory enforcement, the enforcement court adopted our opinions and ruled to terminate the enforcement of the infringement judgment without transferring any funds to the patentee, effectively avoiding substantial economic losses for the client. Meanwhile, the invalidation decision was upheld in the first and second instances of administrative litigation. Subsequently, the Supreme People’s Court took over the case and, through the retrial procedure, revoked the first and second instance infringement judgments, ultimately "bringing the case back to life."
(11)From 2021 to 2022, represented a renowned European enterprise in the communications field in a series of digital signal coding invalidation cases, achieving a comprehensive victory and facilitating a settlement between the parties.
(12)From 2021 to 2022, represented a renowned Japanese enterprise in the communications field in a series of telecommunication call invalidation cases, securing a comprehensive victory and facilitating a settlement between the parties.
(13)From 2021 to 2022, represented a well-known domestic internet company in a patent invalidation case involving a barcode communication method and two trials of administrative litigation, achieving a comprehensive victory.
(14)From 2021 to 2022, represented a renowned Canadian sensor enterprise in an invention patent invalidation case, securing a victory.
