How we treat your personal information
Mentor Graphics considers all information collected to be our information. It will be collected from you via the forms in various locations on Mentor Graphics websites and from your voluntary participation in product improvement programs, but will not be shared with, bartered, or sold to any third party.
At times, we disclose relevant information about our customers to our contractors in order for them to provide specific services for Mentor Graphics, or to distributors to fulfill a customer order. Our contractors and distributors are bound by strict contractual requirements to keep all information they receive confidential and to use such information solely on behalf of Mentor Graphics. We take reasonable measures to protect the information you share with us from unauthorized access or disclosure.
We collect information from you for the purposes of fulfilling your requests, improving your experience on the Mentor Graphics websites, improving our ability to create individually relevant communications to you about our products and services and improving our products and features to help better solve design problems. You may choose to not supply any personal information to us; however, doing so will limit your access to certain content on our site.
How we treat email lists
Mentor Graphics maintains several e-mail lists to keep interested persons informed about events and other items of interest. Individuals can sign up to join our mailing lists in several ways, for example; in response to an email message or by using a form on our website.

How we handle your information changes
We realize that your personal information, including name, company, and email address, is subject to change over time. In the effort to keep your information current and accurate, we are working on tools that, once deployed, will allow you to review your information and update it as needed. In the meantime, if you need to update your information in our records, please send email to firstname.lastname@example.org.

- A physical or electronic signature of the user whose material was removed.

At such time, Mentor Graphics will replace the removed material and cease disabling access to the removed material, unless we first receive notice from the person who submitted the initial DMCA Notification that such person has filed an action seeking a court order to restrain the alleged infringer from engaging in infringing activity relating to the material on the web site.
