Success Stories

Strategic Portfolio of Core AI Algorithm Patents
This enterprise holds multiple proprietary technologies in core AI domains such as deep learning, natural language processing, and computer vision but previously lacked systematic patent protection. We developed a three-tier patent strategy (core + defensive + peripheral), identifying 50+ high-value technical points through deep technology mining to build a comprehensive patent portfolio covering the full AI stack, establishing a robust technical barrier and industry moat.
Innovative Structural Protection for New Energy Batteries
The enterprise's next-generation power battery achieved major breakthroughs in cell structure, thermal management systems, and BMS control strategies. Facing an urgent situation where the product is about to launch but patent protection is not yet in place, we utilized the utility model fast-track review process to complete a patent portfolio covering 12 core technologies within 8 months, providing solid intellectual property assurance for a smooth product launch.
Cross-border patent strategy for the biopharmaceutical industry
The company's self-developed innovative targeted drug has entered Phase III clinical trials and requires patent布局 across major pharmaceutical markets including the US, Japan, Europe, South Korea, and Australia. Through PCT international patent applications, we orchestrated a global patent protection strategy, coordinated with law firms in 5 countries to complete national phase entry, and successfully built a comprehensive global patent protection network, clearing intellectual property barriers for the enterprise's overseas commercialization.
Patent Cluster for Intelligent Manufacturing Robots
This enterprise's independently developed six-axis industrial robot has achieved breakthroughs in core technologies including reducer structure, servo drive, motion control algorithms, and force sensing. We provided comprehensive patent protection services spanning mechanical design to control algorithms, employing a layered layout strategy to build a patent cluster and successfully establish an intellectual property protection system covering the entire robot industry chain.
IoT Sensor Patent Fast-Track Authorization
The enterprise plans to apply for the National High-Tech Enterprise certification before year-end and needs to accumulate a sufficient number of authorized patents in a short timeframe. Its IoT sensor module features multiple innovations in structural design, signal processing, and low-power solutions. By leveraging the utility model expedited examination channel, we enabled batch patent authorizations, helping the company successfully obtain high-tech enterprise certification while establishing an effective technical protection barrier for its products.
Medical Device Patent Infringement Case
The enterprise's core patented technology for high-end CT imaging equipment was infringed upon by 3 companies, with violations spanning multiple provinces and cities across East, South, and North China. We assembled a specialized enforcement team to coordinate joint actions with law enforcement agencies in various regions. While countering the opponent's request for patent invalidation, we successfully secured evidence of infringement, achieving a comprehensive victory that protected the company's market position.

Frequently Asked Questions
Get clear answers on common patent application questions: timelines, costs, and rejection handling.
How long does it take to file a patent application?
Patent examination timelines vary by type: utility models are typically granted in 6-12 months, design patents in 4-8 months, and invention patents generally take 1.5-3 years due to substantive examination. When eligible, you may apply for accelerated or pre-examination channels to significantly shorten the process. We will evaluate the optimal filing strategy for you during the technical disclosure phase.
How are fees for patent agency services structured?
The total cost consists of two parts: official fees paid to the China National Intellectual Property Administration (application, examination, and annuity fees), and service fees charged by the agency (for drafting responses to office actions, etc.). We will provide a written quotation before signing the agreement, detailing each fee. No additional charges will be incurred during the service period without prior agreement.
What should I do if my patent application is rejected?
After receiving an Office Action or a final rejection, we first analyze the grounds for rejection and evaluate opportunities for amendment and response. We can pursue grant through argumentation and claim amendments; if rejection persists, we will file a request for reexamination within the statutory deadline. Prior to engagement, we conduct prior art searches to mitigate high-risk applications and reduce the likelihood of rejection.
What documents are required to file a patent application?
Core materials include the technical disclosure document, covering technical solution descriptions, drawings, and differentiators from prior art. Inventors do not need to draft legal documents; our agents will prepare the claims, specification, and other application files based on the disclosure. Individual applicants must provide proof of identity, while corporate applicants need only submit their business license and inventor information.
Will my technical proposal remain confidential after I engage an agent?
Yes. We can sign a non-disclosure agreement (NDA) before engagement. All technical disclosure materials are accessible only to the assigned attorney during representation, with case systems managed via role-based access controls. Patent agencies and practitioners are legally obligated to maintain confidentiality and will not disclose your technical information to any third party without your consent.
What do I need to do after my patent is granted?
An annual fee is required to maintain patent validity after authorization. We provide monitoring and reminder services for these fees. Additionally, we offer value assessment, licensing and assignment facilitation, and infringement alerts tailored to your needs, transforming patents from mere certificates into operational assets.
