You may want to think about filing a provisional patent if you do not have all the best practices formalized.
A provisional patent application allows filing without any formal patent claims, oath or declaration, or any information disclosure (prior art) statement (1). It provides the means to establish an early effective filing date in a non-provisional patent application (2). It also allows the term "Patent Pending" to be applied.
According to some schools of inventing a provisional patent application is a low-cost alternative or a preliminary step before filing for a non-provisional patent that gives one additional year of protection or grace - maybe enough time to test market your invention before investing in the cost of a regular patent.
There are advantages and disadvantages to a provisional patent application - learn about them before making your decision. A provisional patent application should always be as complete as possible as compared to a non-provisional patent application, however, you will not need to file any claims.
