these patents should not be allowed, they are to broad an idea to be uniquely innovative
Inspection at patent offices seems to be weak to non-existent, which helps the trolls. The mere fact of a patent having been applied for is often sufficient to discourage new market entrants, because even if it's fairly obviously without merit, you still have to spend a pile of money on lawyers to challenge it either before designing your own product or after the incumbent player launches vexatious litigation when you come to market.
Many of these patents should not be allowed, they are to broad an idea to be uniquely innovative. SRAM having the same battery for front and rear derailleur is an example. That’s ridiculous.
