Imagine yourself wandering through a library filled with millions of books on every imaginable topic. Finding the specific piece of information you seek can be overwhelming, right? The same applies to patent databases. But fear not! With the right strategies, you can transform that vast library into a treasure trove of relevant patents. Here is how to narrow down your search and unearth the gems you need.

You need to master the art of keywords. First start broad by beginning with keywords describing your invention's core function or components. Then explore synonyms and related terms to capture different ways your invention might be described. Gradually add keywords representing unique features or technical details.

For example, if you have invented a novel box to store jewelry, you need to look for not just novel boxes in the prior art, but also containers, receptacles, cases, storage space, compartment, organizer, tray, holders, and so on.

As a next step you can leverage classification codes. Patent offices categorize inventions and each patent belongs to a specific classification code. Research classification codes related to your field and incorporate them in your search.

For example for your novel box to store jewelry, you may have to look for patents with the below classification codes.

D09 – Packages and containers for goods (US Classification)

206 – Special receptable or package (US Classification)

206/6.1 - For Jewelry (US Classification)

A45C11/16 - Jewel boxes (IPC/CPC class)

As you move further, never forget inventors and assignees relevant to the subject matter you are dealing with. Target specific inventors known for work in your field and focus on companies developing similar technologies.

For example, if your invention relates to a novel feature in smartphones, then you need to look for patents held by major players in the industry such as Samsung, Apple, Qualcomm, LG Electronics and Google.

Citation Analysis and following the breadcrumbs can also be helpful. You can explore patents cited by relevant results. They often reference prior art or related inventions. You can use forward citations to find patents citing the ones you found, uncovering further developments.

By using above methods and steps, you will transform your patent search from a daunting task into an efficient and rewarding experience.
