For Stephen, the idea or more specifically the need for the DeadBolter was a long time coming. Growing up he saw his parents’ property managers use their keys enter our house at will regardless if we were home or not. While in the Army he was trained in many areas including counter espionage, personal security, personal safety, and travel safety. Throughout life he traveled a lot for work in both his military and civilian jobs. He frequently wished there was some way to ensure no one could enter while he way out. Numerous times he had to take folders, laptops, even larger cases with him because he could not secure the door from outside.

In 2018 Stephen’s combat injury also caught up to him and needed spinal surgery. Stephen decided that he wanted to focus solely on being an entrepreneur and inventor when he recovered. Covid19 happened before he recovered, and Stephen invented and founded Filter19. Sometime after the vaccine was discovered while at a hotel/motel his room was double filled, and a family walked in on him. He looked online for something and there are very few options. Those little travel bar add on lock will not prevent an average 100 lbs. person from pushing it open, and only if gap is wide enough. The bars are bulky, the wedges must have an appropriate gap. Those types will work on outward opening doors. The cables and tapes to secure the deadbolt can be wiggled open. And nothing could be operated from outside.

After weeks of research through all the available options, their claims and reviews. Version 1 was born, however it could not open and close it only secured the deadbolt closed after it was locked from the outside. After weeks of building, cutting, and shaping it was built in real life. After testing it in numerous homes, dozens of different hotels, and all the different display doors as hardware stores like Home Depot. It worked as expected except it only worked on about 50% of older houses and 60% of hotels and 80% of display doors. Some major modifications were done, and Stephen thought version 1.1 fixed the issues. It did for most door configurations unfortunately hotels were only marginally increased.  Version 1.3 an almost complete ground change now provided for almost 100% compatibility across the board. Version 2.0 was the biggest breakthrough in features and usefulness. It gives the ability to remotely open and close the deadbolt and adds a local push to open/close button was placed on the DeadBolter itself to act as a portable mobility assist to turn open and/or closed even without a cellphone. He paid for a professional patent search which came back very favorable. He then had his patent attorney file for his non-provisional (real) patent, and now The DeadBolter version 2.0 is near its pre manufacturing stage. And positioned to explode in a newly self-created multi-billion-dollar market.
