Posts Tagged: "patent numbers"

The day starts out quiet enough. I wake up and scoop my contacts out of the Clear Care® contact lens solution they’re swimming in. Blinking rapidly to settle my contacts, I focus on some tiny numbers printed on the contact solution box. Patent numbers. I’ve been using the solution for years and wonder how old the patents must be. I do a quick Google search and discover that the patents have expired. Strange that expired patents would be printed on the box… My 3 year old interrupts my thoughts as she walks up to me still rubbing her eyes, complaining that her Goodnite’s® Sleep Shorts are soggy. Knowing that absorbent products containing hydrogels with ability to swell against pressure don’t change themselves, I quickly get her some dry pants. Doing so, I check the box and sure enough, more expired patent numbers.
