In Part 1 of this post, I discussed various advantages of provisional patent applications, which are a growingly popular initial filing option for applicants seeking patent protection. These advantages include: establishing a filing date without starting the patent-term clock, obtaining additional time (e.g., to study the market, raise funds, etc.), delaying further costs associated with a regular application, delaying examination, and avoiding the need for immediate formalities, among others.
Yet, despite the numerous advantages of first filing provisional patent applications, there are also various disadvantages that companies and inventors should keep in mind when developing a patent filing strategy and deciding the role of provisional patent applications in that strategy. Some of these disadvantages are described below.
Since 1995, the United States has allowed patent applicants to file provisional applications as an alternative to filing non-provisional utility patent applications (often referred to as “regular” or “conventional” applications). Provisional applications, which are typically less formal and therefore less expensive to prepare, have become a popular initial filing option for applicants seeking patent protection.1 Yet, despite their popularity, deciding whether to first file a provisional versus a regular, non-provisional application remains a dilemma for many companies and inventors. There is, indeed, more than just initial cost to consider in making that decision.
The following are several advantages you should keep in mind when developing your filing strategy and deciding the role to be played by provisional applications. Disadvantages of provisional applications will be covered in a separate, forthcoming post.
