Brief introduction to the case:

In March 2019, Beijing Unitalen Law Office accepted the entrustment of Beijing Zulin Formwork & Scaffolding Co., Ltd. and filed a request for invalidation of the patent for invention entitled "Gate slot construction method and device for gate" of the patent ZL201310018684.3. In the invalidation procedure, with sufficient favorable evidence and invalidation reasons, Unitalen explained in detail that the patent involved did not meet the authorization conditions to the CNIPA. The CNIPA issued No. 41305 Decision for Invalidation on July 31, 2019, declaring all the patent rights involved invalid. The specific reasons are as follows:

The technical solutions claimed in Claims 1-13 are unclear and do not comply with the provision of Article 26, Para.4 of the Chinese Patent Law. Accordingly, the Description does not give a clear and complete explanation to the technical solutions claimed in Claims 1-13, which does not comply with the provision of Article 26, Para.3 of the Chinese Patent Law.

The patentee Chengdu Alang Technology Co., Ltd. refused to accept the Decision for Invalidation and filed an administrative litigation to the Beijing Intellectual Property Court. The court rejected the plaintiff's claim on July 28, 2020.

Recently, Unitalen Law Office received the final judgment of the Supreme People's Court on the second instance of the case, which upheld the above Decision for Invalidation, and determined all claims of the patent involved invalid for not complying with Article 26, Para.3 and Article 26, Para.4 of the Chinese Patent Law.

Comments made by the attorney:

This case is an exemplary case in which the formal reasons in Article 26, Para.3 and Article 26, Para.4 of the Chinese Patent Law are applied to successfully invalidate the patent right for invention. From the invalidation stage to the first and second instance of the administrative litigation, Unitalen always insists that the subject of judging whether the claim is clear and whether the Description is clear and complete should be those skilled in the art with corresponding knowledge and ability, instead of the patentee himself, helping the customer win the final victory of this case.

Case brief:

On behalf of the client, Unitalen filed a request for invalidation to the CNIPA for the Chinese patent for utility model entitled "Press Barrel Assembly of Juice Machine" in December 2018. The reasons for invalidation include: the disclosure of the Description of the patent involved is insufficient, the claims are not supported by the Description, and the claims do not possess novelty or involve an inventive step. After oral hearing, the CNIPA made an examination decision on the request for invalidation in June 2019, which determined that: for those skilled in the art, the technical solutions of the present patent are vague, unable to be implemented and realized. Therefore, the technical solutions defined in the claims of the patent involved are not fully disclosed in the Description, which does not comply with the provision of Article 26, Para.3 of the Chinese Patent Law.

The patentee filed an administrative litigation to the Beijing Intellectual Property Court in September 2019 in response to the above examination decision on the request for invalidation. In the interpretation of "full disclosure" of the patent Description, the patentee put forward a completely different observations from the patent invalidation procedure. After the hearing, the Beijing Intellectual Property Court upheld the above examination decision on the request for invalidation in December 2020 and rejected the plaintiff's claim.

The patentee refused to accept the first instance judgment of Beijing Intellectual Property Court, appealed to the Supreme People's Court in early 2021, and put forward different observations in the interpretation of "full disclosure" of the patent Description from the patent invalidation procedure and the litigation procedure of first instance. After trial, the Supreme People's Court made a final judgment in December 2021, rejecting all the appellant's appeals and upholding the original judgment and the sued decision.

Case analysis:

In the patent invalidation procedure, the first instance procedure and the second instance procedure of the administrative litigation in the patent involved, the focus is whether the Description of the present patent fully discloses "the size of the juice outlet hole of the juicer is adjustable".

In the final judgment of the case, the Supreme People's Court further clarified that when judging "full disclosure" of the patent Description, generally speaking, the Description should clearly and completely explain the key improvement points of the patent involved. In the case that the Description does not disclose the specific technical means and does not give clear guidance, based on the common knowledge or the conventional technical means in the art to realize the basic functions of the key improvement points, the key improvement points should be relatively determined as far as possible, and should not be realized in different ways by those skilled in the art through different imagination. In particular, the patentee is not allowed to explain this with different expressions in different procedures to expand the protection scope of the claims.

At the beginning of the Spring Festival, service provided by Unitalen was praised by customers again - Sungrow Power Supply Co., Ltd. awarded Unitalen the honorary title of "Excellent Agency in 2021", awarded Unitalen patent attorneys AN Miao and HU Suli the title of "Golden Attorney in 2021", and CHEN Ying the title of "Rising Star Attorney in 2021".

Depending on the situation of the individual cases, the party may, according to the circumstances of the court trial, submit the Post-trial Attorney's Opinions within the specified date after the court trial, and the specific date shall be subject to the notice of the collegial panel.

III. First instance judgment stage

The above process is based on our daily handling experience and relevant legal provisions, and the actual trial of the case is not subject thereto.
