This is very interesting information, Joe. It clarifies in more detail
the fact that this entire lead-free movement was a planned scam for a
bunch of hucksters to make millions at the expense of the general
public.
Not one iota of "preventive medicine" will come of it. There will be
very little benefit to all of us from an environmental standpoint.

Subject: [TN] Lead-free patent activity - FYI

Greetings all,

I took a look the other day at US patents to see what was happening on
the lead-free front and senses the size of the minefield was being laid
out for future legal battles as lead-free products are being rolled out.

I did a quick search using the limiters of:

Lead free OR leadfree OR lead-free AND solder AND  circuit,

It is admittedly not perfect but it was done in a manner to to try and
focus the search on electronics related filings and hopefully filter out
things like paint, gasoline and pipe.

The same search was performed for each of the 14 years back to  1992
which is about when the lead-free campaign began.

Here are the results:

Year         No. of  patents

1992     =      3

1993     =      9

1994     =      8

1995     =      21

1996     =      11

1997     =      13

1998     =      20

1999     =      25

2000     =      32


2001     =      58

2002     =      92



2003     =      135

2004     =      165

2005     =      159

Total     =      751

It appears that there was an early surge around the time the US
government first expressed a willingness to listen to the argument for a
band on lead and then a slow down that roughly corresponds with US
government's  realization that there was no scientific evidence that
lead in electronic solder  was a problem and then another surge in
patents that has accelerated since  the EU made known their intentions.



Now here is the kicker...

There are more than 1100 published US patent applications currently
pending issue using the same search criteria. The number of suppressed
US patent fillings and foreign patents would surely have added
significantly to the tally.


Best wishes,
Joe
