To track recent filings by industry, you can visit the Industry Center for a particular industry group. The industry center will display the five most recent filings involving companies in that industry.
For a more detailed breakdown, the Litigation Watch home page lets you search by industry and sub-industry groups. For example, if you wanted to track litigation involving technology companies, you would select "Technology" in the "By Industry" drop-down menu, and click on "Search!". To narrow your search to just "Computer Software and Services" companies, select that sub-industry instead.
From the Litigation Watch home page, you can also search for filings by company. Enter the name of a company in the "By Company Name" box or enter the stock ticker of a company in the "By Stock Symbol" field.
