Trademarks are registered under specific categories of commerce. It's within those categories that trademark confusion can be argued.

Comcast has like 50 trademarks (look them up on TESS), and they impact on everything from cable to internet services to hats and coffee mugs, basically anything the company makes or does. Let's take COMCAST BUSINESS as a random example. This trademark is registered for a variety of categories for which confusion can easily occur, but one stands out (italics mine):

> "IC 009. US 021 023 026 036 038. G & S: Downloadable cloud-based software used to back up business data; downloadable cloud-based software used to share business data; downloadable cloud-based software used to send and manage secure documents; *downloadable cloud-based software used to manage, secure and protect computer networks;* downloadable cloud-based software used to create and transmit documents with electronic signatures; downloadable cloud-based software used to manage telephone systems; downloadable cloud-based software used to manage advanced telephone features; downloadable cloud-based software used to provide web conferencing; downloadable cloud-based software used to monitor business security systems; *downloadable cloud-based software used to detect and remediate computer viruses, worms, trojans, spyware, adware, malware and unauthorized data and programs;* high-definition multimedia interface cables; and Ethernet and wireless networking hardware and computer hardware and components thereof."

Then there's this one:

> "IC 038. US 100 101 104. G & S: *Providing high-speed access to the Internet, mobile networks, wired and wireless networks and other electronic communications networks;* telecommunication access services; telecommunications gateway services; wireless broadband communication services; wireless broadband telecommunications services; telecommunications services, namely, voice, video, and data transmissions provided through the use of cable television distribution facilities; telecommunication services, namely, transmission of voice, data, graphics, images, audio and video by means of wireless communication networks; *high-speed electronic data interchange services provided via modems, hybrid fiber coaxial cable networks, routers, and servers;* electronic, local and long distance transmission of voice, data, and graphics by means of cable, telephone, wireless, ISDN, and technologies; telephone communication services; providing voice communications services via cable, fiber optics, the internet, wired and wireless networks, mobile networks and other electronic communications networks; providing fiber optic network services; Voice over Internet Protocol (VoIP) services; cable television services; cable television broadcasting services; cable television transmission services; providing access to telecommunication networks; provision of telecommunication access to video and audio content via video-on-demand, interactive television, pay per view, and pay television subscription services; video-on-demand transmission services; video conferencing services; wireless PBX services; cloud-based PBX services; streaming of video and audio material via the Internet, wired and wireless networks, mobile networks and other electronic communications networks; telecommunications services, namely, providing advanced calling features and leasing or rental of telecommunications equipment; leasing or rental of telecommunications equipment; computer network access services by means of a metro Ethernet; electronic transmission and streaming of digital media content for others via the Internet, wired and wireless networks, mobile networks and other electronic communications networks; cloud-based communications services in the nature of instant messaging, telephony, audio and video conferencing, screen sharing, file transfer, call control and management, voice mail, e-mail, SMS and facsimile services; and providing wireless hot spots."

And that's just the first thing I picked out. It goes on like this. So, yeah. Comcast the network degradation simulation software almost unquestionably overlaps with Comcast's trademarks.
