    tough time ahead for Tessera

    the coming patent reform will kill its abusive business practice and dry up it revenue. the expiration of its electronic packaging patents also kill it. It has no interest in innovation as claimed; it only has interest in patents. they abuse US patent system to file a few patents with no innovation at all just some common senses, since the US patent has no technical capability to verify their so called innovation.

    • Have a look at the patents filed with the USPTO. This is not what anybody 'claimed' this is what IS. The comment I made about you not doing your dd was made for a reason. Some people prove their own ignorance. Congratulations, here's your sign.

    • that is just what Tessera claimed. Do you really believe what it say? ignorant.

    • TSRA was founded by two IBM research scientists, DiStefano and Kandros. The uBGA technology was actually linked to Motorola at one time not IBM. They have several hundred key patents invented in-house by TSRA employees and are still being paid on them today. Your assertion that they don't have any in-house technology is uniformed and ignorant. Learn the game rookie. I've been on this board for years and ALWAYS appreciate a counter opinion that makes sense. tesserana obviously has not done his dd or he would have his facts straight. I'll help you with the basics.

      The fact that thermoelectric cooling didn't work 40 years ago is completely irrelevant today and the assumption that it somehow applies is absurd. Thats like saying we couldn't get to the moon in 1950, so why bother trying in 1969.

      Theres nothing worse than an engineer that thinks if he can't make it work, nobody can. Just message board nonsense. Lets not overlook that the cell phone in your shirt pocket was hype once too. And you bought it, didn't you.

      jacosa - good info, thanks.

    • Thermoelectric is a different technology entirely. It isn't really all that efficient. I've played with some application ideas, and they never worked out--because of power needs.

      The only hype I recall seeing on Tessera (before the recent Cramer flap) was on the bear side. Back when the reexamination of the key patents for currently-sold technology was being announced, there were a lot of "Sky is falling" stories around. I've been there before: the PTO talks funny and the sky wasn't (and most likely isn't) falling. Cramer is just a jerk (a smart and experienced jerk, so sometimes the beginnings of his rants include useful observations, but once his emotions kick in HIDE). Best to pretend he never mentioned TSRA. Current price, if I recall correctly, is around where it was before he kicked it around.

      The key point in ionic cooling is that -today- it is possible to make an air mover that works as well at moving air inside a thin notebook computer form factor as a fan does. By fiddling with design rules and taking advantage of multiple wind sources, comparable cooling can be obtained for half the power drain, and it is silent. Fans scale badly as you go thinner (axial flow fans move little air and radial flow fans develop friction problems), but Tessera claims that corona breeze devices scale down well. At the very least, there will be a demand for corona wind devices in thin, quiet notebook devices and in notebook-or-smaller devices with very high video performance. Licensing such technology might not be enough to makea new company, but it's real business for an existing one.

    • It is hard for me to get your points. if tiny, thermal electrical cooler is a very efficient device. Using my all knowledge and searching web sites, I could not figure out how to enhance the air circulation (than air diffusion) to effectively cool a device. I lost lots of money on hyped companies. Using all my knowledge and experience, I think this tessera is a very hyped company.

    • Good points. The tessera north america (part of tessera) is an evil company. it is controlled by a few crackpots. they could not make wafer level camera; but blame the test guy could not test them with a high MTF. They blame me that I could not support their nonsense in my work, because I told them what they made are just craps.

    • Finally a specific issue. You say, in brief, "Someone tried something like electrostatic cooling before and it didn't make it commercially, so it's old technology that doesn't work."

      Of f'ing COURSE there are old failures in electrostatic cooling. I personally learned about corona breeze effects back around 1960, and the observation was probably more than a century old back then. Interesting effect and one that has always seemed to have possibilities. So a lot of ideas got patented. And since then, there have even been electrostatic-wind-cooled computers built (I've read detailed project descriptions). And it was none of it industrially feasible. And as you said, fans are pretty good.

      When they get really tiny, though, fans become crap. Like, when they get down to sizes appropriate for pocket electronics, or for placement inside dense electronic assemblies (like graphics processing boards). And since the last round of interest in electrostatic air moving, the technology of generating the high voltages (at tiny current) required has been revolutionized (start by searching "charge pump"). And the design of air flow devices has moved from a rule-of-thumb era to a computer simulation era. So some engineers started looking at what can be done today, and voila! Tessera has patents on a technology for moving air at about half the power consumption (they say) of a fan on the scale of a notebook computer, and it can scale downward. And as a bonus, it's noiseless. That is a real invention, and it has plenty of potential to become a real business. Finding USEFUL ways to exploit an effect that everyone knows about is EXACTLY what the patent system was meant to encourage and reward.

      Was the technology for Tessera's current patents invented at IBM? I dunno. Somehow Tessera wound up with the patents, and they clearly solve problems that come up repeatedly. Back in the 1990s Kyocera owned the chip packaging business, and something had to happen to take it away from them.

    • tesserana is bloody well informed, I think we should listen. Obviously knows a lot about the company.
      Thanks for posting and keep up the good work.

    • do not just buy the hype. I looked at the electrostatic cooling technology. I found that a few patents filed by Oscar Blomgren in 1960s. It is an old technology, but never materilized. the fan is very efficient forced convectional cooling method. To realize the air circulation in electrostatic cooling is a difficult job. Do not get fooled by the fancy name. I wish they could come up a few real technologies, than use litigation to intermidate other companies. The patent reform is led by IBM. Tessera's electronic packaging technology is from IBM around 1990s. You now know why these big techs are so tired of these patent troll. the patent troll is a mild name; actually they are patent vampires in these low profit margin era.

    • Thanks, techinvestor05, and I will of course extend the same respect to you, even if we disagree. These Yahoo boards are useful if posters provide useful information, including opinions, since no one has the investment equivalent of "Back-to-the-Future" issues of next year's Wall Street Journal. I get turned off by the immature name-calling that some resort to. For what? We all are strangers with one thing in common, obviously -- an interest in the prospects of listed stocks. So, good luck to you. I don't have a position in TSRA (never have). And I'm too old to load up on high PE plays. I just know something about the company's chip packaging patents as a patent lawyer. That's why I come here occasionally -- to get caught up on the pending cases. I no longer represent any adverse party.
