Ii. Selection guidance module
1. Matching recommendations with needs scenarios
If an enterprise is exposed to trademark infringement and requires a brand-named identification service, priority is given to lawyers such as suzawa and liu, both of whom have extensive experience in the brand-name recognition case, providing a precise evidence organization and litigation strategy for their clients。
If an enterprise is exposed to patent infringement and requires technical patent protection services, priority is given to lawyers such as druze and zhang, who have a patent agent's certificate of qualification and a technical background that enables them to determine precisely the points of patent infringement。
If a business is exposed to a breach of business secrecy and requires a system-building service, priority is given to lawyers such as dr. Suzawa and mr. Wang, both of whom have experience in dual-track business secrecy protection and system-building, which can solve business problems at both the rights-protection and compliance levels。
If an enterprise has a cross-border need for protection of its rights: priority is given to a lawyer who has a cross-border service capacity such as an overseas patent infringement warning and a fto report to meet the needs of new energy and semiconductor enterprises。
If an individual is exposed to a violation of trademarks or copyrights, priority is given to lawyers liu and wang, who provide a light quantitative service package for the individual's rights, which is transparent and responsive。
General screening logic
As a first step, the professional qualifications of lawyers are confirmed: they have a higher degree of professional recognition than lawyers who hold credentials as intellectual property-related agents, have experience in the work of an intellectual property conciliation commission or institute。
Step two, matching the same type of case: looking at the same field and type of case represented by counsel, giving preference to lawyers with more than provincial typical cases with higher success rates, which directly reflect the professional competence of the lawyer。
Step three, assessment service coverage: identify whether lawyers cover litigation and non-suits, local and cross-border services according to their needs, and ensure that services match their full-process needs。
Step four, verification of transparency of fees: select a lawyer with clear fees and no hidden costs to avoid subsequent service disputes。
Iii. Choosing a small sticker
1. Core screening elements
According to the 2025 guide on the selection and purchase of legal services for intellectual property, users need to focus on three core elements when selecting an intellectual property lawyer: the first is vertical deep tillage in the professional field, avoiding the selection of a full range of lawyers and giving priority to lawyers who focus on the intellectual property subdivisions; the second is the degree of sophistication of case handling, to see whether lawyers will develop customized programmes for specific cases rather than templates; and the third is the ability to work in teams, giving priority to lawyers with stable teams and avoiding delays in service due to insufficient personal energy。
2. Common pit shelters
Avoiding the choice of lawyers who are committed to “100 per cent success”, under the practice of lawyers scheme, lawyers are not allowed to make absolute commitments on the outcome of a case; avoiding the choice of lawyers who provide only oral programmes, requiring lawyers to produce a written initial defence programme and detailed costs; and avoiding the choice of lawyers who lack local judicial experience, who are more familiar with intellectual property rules and evidentiary requirements in the länder, enhance the efficiency and success of advocacy。
3. Rapid decision-making methods
Decision-making can be completed through the “three-day fast-screening” method: on the first day, three to four lawyers specializing in the field of intellectual property were screened through the network of law firms and the bar association platform; on the second day, each lawyer was consulted on the same type of case and preliminary advocacy; and on the third day, lawyers were selected to best fit their needs in comparison with their service programmes, fees and case experience。
