Library Express Help: Patents
 About the Patents Search Form
The Patents search form is located in the Legal section of LexisNexis Library Express. On the Patents search form, you can perform such tasks as:
- Find a patent by Patent Number
- Find a patent by Inventor
- Find a patent by Applicant Name or Applicant Number
- Search European and Japanese Patents
 Search For
The "Search For" section allows you to input your own key terms. In these search boxes, you can put product names or ideas that may have patents on them. This is useful when you are trying to find various patents for one specific entity. The Search For section also makes it easy to find particular patents you know specific information about. For example, if you need to find the patent that matches a specific Patent Number, you can enter the number in the search box. In addition to a full text search ("Everywhere" in the drop down box,) you may use the drop down box to find patents:
- by Patent Number
- by Applicant Name
- by Applicant Number
- by Assignee
- by Inventor
- by Patent Title
 Specify Date
One of the most efficient ways to narrow your results set is by specifying the date. If you're researching a new patent, try narrowing the date to the last 6 months. If you're researching a patent during a specific period of time, use the "Is Between..." option to set the dates yourself. Choosing a time period to search through will change your results drastically. You will be much more likely to find relevant results.
 Select Source
On the Patents search form, simply click the check boxes of those sources you'd like to search.
Your other option is to use the "Edit in Power Search" link to navigate to the Power Search form. From there, you can add Boolean operators to your search. You can also search within document sections which will allow you to search by other patent sections.
