Acquisition of intellectual property rights

Prior to filing an application, Kyowa consults with the client to obtain a full understanding of the client’s business strategy in order to be able to provide a foresighted, cost-effective patent strategy in support of establishing business-efficient intellectual property rights.
To help our clients build efficient and powerful networks of intellectual property rights, we have established a system in which not only our patent attorneys but also our attorneys at law and research staff work together to provide support and insight at the invention stage.
For better visibility of the contact person, a team leader is assigned to each client. The team-based model also helps with both sharing and centralizing information in accordance with the circumstances of each case. Through cross-departmental cooperation and collaboration as needed in each case, we are able to accommodate increasingly complex and diverse technical cases.
