Yes. Since I am actually a certified Software Asset Management specialist for Autodesk, I can tell you exactly what this means.
This part of the LSA is talking about Network Licenses. If you have stand-alone licenses then this doesn't apply to you. It is only for network activated seats where your license is not on the client but actually runs in the Autodesk Network License Manager on a server (LMTOOLS) and is an additional cost for this kind of licensing.
What network licensing allows is for you to activate your licenses on a server. This means that if you have 5 seats of Autodesk products, you configure a license on a server using the license manager to serve those 5 seats to any 5 users in your company. Once the 6th user tries to launch the product, they get denied. It is self-policing. You are able to install the network version of the Autodesk product on an infinite number of company-owned clients because the license exists on the server and not the client. Only the permitted number of seats can run and no more.
To break it down:
Needs, only so long as the maximum number of concurrent Authorized Users does not exceed the Permitted Number of Authorized Users or other limits imposed by the Autodesk License Manager
The License Manager imposes the maximum number of seats. Again, if you have a 5 seat network activated product, then the license manager will allow 5 clients to connect and deny all others after the maximum number of concurrent users have been reached. If client #6 wants to use the product, another person must close the software before the License Manager will let them access the software.
If the License Identification identifies the License Type as “Network" or “Multi-user”, then Licensee may Install copies of the specific release of the Licensed Materials designated in the applicable License Identification on a Computer and permit Access to such Licensed Materials on multiple Computers, on a Networked Basis, solely by Licensee’s Personnel, solely for Licensee’s Internal Business Needs
This means, if you have network seats, then you can install the product on an unlimited number of clients that are controlled by your company. You cannot use these seats for customers, subsidiaries, or equipment & employees not directly owned by your company.
Hope that clears it up.
