Trade Marks and Trade Names
We believe that identity means everything to succeed in a competitive economy. Therefore, we advise our clients to register their Trade Marks and Trade Names. Further to create a Logo to distinguish their businesses and their products from those of competitors. A trademark is one of the most important business assets. When our clients register their Trademarks or Logos, they create a monopoly over its use which is fully protected by Law.



Industrial Design registration protects the appearance of new and distinctive designs used commercially. A design relates to the features of shape, configuration pattern or ornamentation which gives the product a unique appearance.  A design can be three dimensional such as a shape of an article or two dimensional such as a pattern or lines. 


If you’re into import and export, we advise you to register your design the foreign country you are exporting to and in Sri Lanka. This would enable our clients to protect their designs from deliberate copying and the independent development of a similar design. We trust that a registered design can be a valuable asset to the business. Registration gives the owner the protection for the visual appearance of a product.
