A patent issue from 2007 ?

Last year I had written the article "Patents for the Online Dating Industry" and other posts like
NEW patent: System and Method for Identifying Other Users After a Termination of a Relationship
How to copycat eHarmony, 13+ years old obsolete site.
The Terrible Cost Of Patents
 * We are in the middle of a patent bubble.
* Technology companies are spending billions of dollars on assets which they need primarily to defend themselves against the rising tide of patent litigation, they won't invest in new products, new jobs, new facilities or other economically productive activities. And by and large, they will not use those patents to create new products.
* What you and I might consider an improvement, a patent lawyer might consider infringement.
* Patents were originally conceived to protect inventors—people and companies who contribute to the advancement of society by creating new products. But in the past decade, something went horribly wrong. Patents are increasingly became nothing more than financial and legal weapons, to be amassed in portfolios by "non-practicing entities" (i.e. patent trolls) and used to extort protection money from economically productive companies.

 
Now OPW writes about "Patent Troll Takes Aim At iDating Industry" talking about the U.S. Patent No. 5,623,660 issued April, 1997.
I thought that issue was solved during 2007, in the article "Suit Says eHarmony, Others Breached Patent" and the post "Goodbye dating patents." from the POF owners.
