My concerns about DIY protectors would be any plastic additives in the plastic used for screen protection. These additives could migrated to the LCD plastic screen and change (read damage) the plastic. The most common ones that I would worry about would be plasticizers - used to make the plastic soft and plyable. I do not believe that vinyl has plasticizers (or any additives for that matter). Most clear plastics tend to not have additives as the additives may affect the clarity of the plastic. So if the plastic used as a screen protector is clear - chances are it's ok to put on your screen.
Adhesives may also have volitile materials in them that could affect the LCD plastic. Any thing that you spray on the vinyl to help it cling could also affect the plastic - water based products are the way to go as they would have little or no affect on the plastic. If anybody uses DIY screen protectors with sprays or adhesives - please post how well it worked and how long it has been on your screen. Effects on the LCD screen would take months or longer to be visible.
A little patent education for everybody - anyone holding a patent must force (with legal action if necessary) anyone infringing on the patent to stop manufacturing/selling. Therefore the longer Nuwrite and Writerite continue selling/manufacturing screen protectors the more difficult it would be for the patent holder get the courts to stop the selling/manufacturing. In other words - a patent holder must aggressively force people to stop infringing on the patent. Since I have not seen any action against these companies, and as time goes on - the patents become more unenforceable. I currently purchase Writerites - I like the feel of the stylus against the plastic. Would like it to be clearer but a good trade off for me.

You have to read this quoted statement. Do not B.S. these people. And if you do not know what you are talking about then don't say anything.
"Dear Bill,
The statute of limitations in patent cases is 6 years. So as long as you sue the infringer within the six
years, you lose no damages off of the back end of the statute of limitations.
There are two defenses to watch out for when enforcing a patent. One is laches, the other is estoppel.
Laches means unreasonable delay in filing suit. The analogy is to the 6 year statute of limitations. If
you sue within 6 years of the time you first were aware of the infringement, the burden is on the infringer
to prove the delay was unreasonable. But if you have been in continuous hot pursuit, the delay was
reasonable, even if it lasts nearly 6 years. If you sue after 6 years from first learning of the infringement,
the burden shifts to the patentee to prove his delay was reasonable. If you have been in continuous hot
pursuit, the delay is reasonable, even if it lasts beyond 6 years. How long beyond 6 years is reasonable
even if pursuit is hot is unknown, is a question of fact, and is decided case by case.
Estoppel is giving the infringer reason to believe you have abandoned your claim against him on which
he has relied to his detriment. Typically it involves charging infringement and then backing off and doing
nothing, leading the infringer to believe you have abandoned your claim. Typically you need about 3 years of total silence and no pursuit after the infringement charge in order for estoppel to kick in. Again, if pursuit is hot and continuous, the infringer cannot reasonably believe you dropped the claim.
We have actively pursued Concept Kitchen by continuous mailings to them and their customers charging infringement and by continuous assertions and attempts to get them to take a license. We have recently attacked Fellowes on the same basis. There has been no staleness or delay in asserting the patent and neither Concept Kitchen nor Fellowes can reasonably believe we have dropped our claim. Both have been recently told they will be sued shortly if they fail to sign a license.
Greywolf is your typical..."
