Intellectual Property (IP) SERVICES

Patent litigation (infringement litigation, provisional dispositions, invalidation trials, rescission of trial decisions, arbitration, customs import suspension, etc.) is one of our strongest fields. Our attorneys-at-law and patent attorneys have collaborated to successfully handle numerous lawsuits across a wide range of technical fields, including life sciences, materials, machinery and equipment, electrical devices, electronic materials, telecommunications, and business models. This includes cases involving cutting-edge technologies like biotechnology and information technology, as well as cases concerning Standard Essential Patents (SEPs) and games, and large-scale cross-border matters.
We also have extensive experience in litigation concerning the Unfair Competition Prevention Act regarding trade secrets and counterfeits, as well as design right, trademark, and copyright infringement. Furthermore, we provide expert opinions regarding the existence of IP infringement and the validity of rights.
We aim to provide the best legal services based on this abundant experience and track record.

As filing procedures for the acquisition of patent, trademark, and design rights in Japan and overseas are primarily the work of patent attorneys, our IP Department has a robust structure in place to handle these matters. For patent applications, patent attorneys well-versed in the technical field of the invention prepare application documents that accurately reflect the client’s needs. For trademark and design applications, specialized patent attorneys advise clients on obtaining the optimal rights for their business activities.
For applications from overseas to Japan and from Japan to overseas, we ensure close communication and coordination with all involved parties and pay meticulous attention to prevent discrepancies in the prosecution procedures.
Strict deadlines are set for various procedures during the rights acquisition process at the Japan Patent Office and overseas patent offices, making deadline management extremely critical. To address this, we maintain a comprehensive support system that ensures meticulous management of all deadlines and processes not only by the responsible patent attorneys but also by the administrative group.

Attorneys-at-law and patent attorneys, well-versed in industry practices and relevant technologies, provide comprehensive support for drafting and negotiating intellectual property-related contracts. Specifically, we handle the drafting of license agreements, technology transfer agreements, joint research and development agreements, content/software production agreements, and the development of internal regulations for employee inventions and confidential information management.
Furthermore, we help maximize the value of clients’ intellectual property by representing them in contract disputes and negotiations, advising on negotiation tactics, and providing advice on brand strategies to enhance corporate value. We also strongly support business development by providing tailored services, including Intellectual Property Due Diligence (IPDD), in M&A and finance deals involving intellectual property, taking into account individual technical and business fields.
