What’s the main change you’ve made in the firm that will benefit clients?

We structure our team so that our clients’ works are reviewed by lawyers and consultants at different levels, ensuring comprehensive results for the legal services ASL LAW provides to clients.

ASL LAW upgrades technology to manage clients’ works, optimizes internal administration to ensure works security as well as client information security. Securing client information and avoiding conflicts of client interests are always ASL LAW’s top priorities.

In addition, realizing that there have been many changes in Vietnamese law recently, we always proactively research and actively consult with clients through private meetings and closed group seminars so that clients can prepare in advance for legal changes from Vietnam. In particular, ASL LAW builds teams of lawyers and consultants who can directly advise clients in their own languages such as English, Chinese, and Japanese.

Thanks to being proactive and having decades of cooperation with foreign partners and law firms, ASL LAW is always ready and well meets the requirements of providing cross-border legal services for Vietnamese businesses when needed.

Is technology changing the way you interact with your clients, and the services you can provide them?

Technology changing has certain impacts on the way we work with clients. Since many of ASL LAW’s clients are foreign ones, the parties often meet online via certain platforms. Technology also creates more favourable conditions for us in signing contracts, sending documents, accessing documents, and increasing information security for the work being handled for clients.

Can you give us a practical example of how you have helped a client to add value to their business?

We have a chance to provide Intellectual property service to clients in the electric auto sector. The client’s specific request is to register patents and trademarks in Vietnam. After accessing information, we built for them a comprehensive strategy on building and protecting intellectual property in Vietnam, namely as follows:

+ We conduct prior market research on technical solutions with technical characteristics related to the technical solution that the client intends to implement to ensure that we can not only evaluate the client’s ability to grant patents but also avoid cases where client brings products to market that infringe on the rights of other parties;

+ Regarding the client’s trademark registration, we build a comprehensive trademark registration strategy to avoid cases where other parties take advantage of the client’s popularity to launch products with similar brands. In addition, after successfully registering the client’s trademark, we put the client’s trademark information into the management software to automatically remind clients to renew when due and also monitor the market to detect any signs of potential infringement of the client’s trademark. In addition, we also watch the database of the Vietnam Intellectual Property Office to detect trademarks that are the same or similar to our client in order to conduct an opposition to that trademark.

Next, we also conduct customs control measures to ensure that no trademark-infringing products or counterfeit products are officially imported into Vietnam.

In particular, client signed OEM contracts with many different companies, so we also help clients build a legal framework related to intellectual property to ensure clients’ rights.

Are clients looking for stability and strategic direction from their law firms – where do you see the firm in three years’ time?
