I just noticed another patent
[www.google.com]
Filing date Mar 16, 2012
"The liquefier assembly of claim 1, wherein the hollow liner compositionally comprises polytetrafluoroethylene."
ie a teflon liner.
"blowing air from a blowing unit toward the inlet end of the liquefier tube;"
"As discussed below, the inlet liner reduces the risk of forming “hot melt weld plugs” at the inlet end of the lined liquefier assembly. This allows cooling air to be continuously directed toward the inlet end of the lined liquefier assembly, reducing the risk of forming “deformed filament plugs”. The reduction or elimination of these plugging issues increases the reliability of printing operations in additive manufacturing systems."
Wasn't this prior art well before Mar 2012?

I worked on some patents in my professional past and I have also studied the 3D related patents in the last months and I published a book on them. I also feel great sympathy for OS and Reprap. There is a vast number of patents that is 3D printing related. Stratasys alone holds over 400 of them. Even for a person that considers himself aquainted with the matter and has an engineering background like me, it is barely impossible to know all of the patent claims that one may have to consider if he wants to bring out a 3D printer. That - in my option - is the major cause for large printer company like HP,Canon,Lexmark etc. why they did not get into this market yet. There are simply very few technologies remaining that have yet not been covered by patents.
Private individuals have nothing to fear from this kind of patent law suits.
But if you are going to set up a business, it is the same game everywhere, wheter you produce cars, refrigerators or .. 3D printers.
If the holder of a patent gets aware of an infringement, he must react within a certain timespan in order to keep his claims upright. In that sense making big KS campains or marketing 3D printersis a risky thing.
If one gets into busines, it could be smarter to ask the patent holder for a licence agreement, even after he was sued and try to find a way to get along with the patent holder. I do not think that those major players are so much afraid of Reprap - type clones. It is a different price segment and I guess even different customer group, that requiers good aftersales service, financing etc.
And let´s be honest: The professional printers are often far ahead concerning features, hardware, software, quality of parts etc. So I assume, it is the danger of loosing the claims of their patent if they do not react. So keep a low profile, try not to copy the appearance of their products (That is really, really stupid and calling for trouble) and if you are beeing approached try to negotiate a licence agreement.
One has to realistic, patent laws are globally and they wont be changed because of enthusiast who don´t want to accept them. This is the truth, even if some won´t like to heart it.

Can you provide a list of orphaned and expired foreign 3D printer patents?
I would enjoy the opportunity to review them.

I did not collect all expired patents, but that is a good suggestion. I call the patent database an "ocean of information". Once you dig into it you will loose yourself in this vast amount of data: Just a short exerpt from my book to give you an idea on how many documents there are. I have not checked it, but many of those patents should be expired today:
I have attached some pages for your reference. again, I have not doublechecked them for expiration, but many of them are from the 1980s and 1990s.

Do you have plans of releasing an English version of your book?
A2
I am working on it. It wont take too long, Most text in this book is english anyway, since most patents themself are in english. Only my explainations and comments on the technical and legal aspects are in german. I will shorten and translate that. I think it will be ready this december.
And I will try to make that document available here on reprap. I am just not too familiar with wikis, GNUs and all that stuff. I will have to ask around and read me in, how this can be done. Sorry for my stupidity, but this kind of collaboration is new to me. So people can download it at no cost and read it through. Maybe that could be some contribution. Thanks to reprap I have a faszinating deltabot here on my desk, which I dreamed of, since I saw the first one at university 30 years ago :-))) But is was completly out of possibilities at that time to build or buy one for me.

The deadline for patents in which a holder can successfully file a cease-and-desist-order is 6 months from the time the infringement came to his knowledge. If he misses that dead line he risks that the whole patent will become state of the art and therefor public domain. He will then loose any rights on his invention.

When a patent owner becomes aware of an infringer, the owner can simply wait until he pleases to bring an infringement suit.

In addition to that, the private non-commercial or educational use of patented technology such as here on Reprap is not an infringement

as i hear it stratasys was actually quite a bit of help to Adrian Bowyer in the early days
Quote
Forrest Higgs
They "asked" as opposed to sending a "cease and desist" notice because a few people in the firm had spoken with several of the core team members on a few occasions. On the impression that these few had of us they convinced the rest that they might achieve the same effect as a cease and desist order informally and avoid the heat and bad feelings that cease and desist orders are wont to create.
Their forbearance in this regard is much appreciated. If Stratasys had been the Mouse (Disney), for instance, things would have gone very differently and much more unpleasantly.
As I said earlier, this was a small thing for them to ask and Dr. Bowyer was more than happy to give them what they asked for. While we can't stop you all from violating the understanding that we have with Stratasys outside of these blogs and forums be certain that we will enforce Dr. Bowyer's undertaking with Stratasys within them.
I'd personally appreciate it if you all didn't antagonise the people at Stratasys. Nothing is to be gained by doing so and a considerable amount of good will is likely to be lost. We have a good working relationship with them and would would like to keep it that way.

Wouldn't it make more sense for Stratasys to first sue Adrian Bowyer, and his company RepRapPro Ltd?
Bringing a lawsuit against Adrian Bowyer (invented the RepRap Project ) would generate a massive amount of free press exposure. I think this is the most efficient approach for Stratasys to get their message out to the hundreds upon hundreds of companies infringing upon Stratasys I.P.

I can say that we are regularly inspired by the innovation created by individual hobbyists.
At MakerBot, we often try to hire and collaborate with clever and smart people.

Perhaps I misunderstand, but based on what I’ve read about the Stratasys vs Afinia claim, it would appear that prior to being acquired, MakerBot violated (at least) the following (claimed) Stratasys patents:
’925 patent by using non-solid infill
’058 patent by using a heated platform
Am I wrong in thinking this? Maybe you were paying royalties to StrataSys?
Also, there’s more than one kind of patent troll. Companies that patent purposely vague or over general ideas qualify in my mind. By reading ’124, you would think StrataSys invented the glue gun.

makomk on December 4th, 2013 at 3:22 am said:
Right, I think I’ve said this before, but Stratsys did not actually invent the things that they’re suing over and that Makerbot are still selling products based on:
- They did not invent the kind of extruder that they’re suing over and that Makerbot are also using. It was originally created and developed by the RepRap community and subsequently by the company whose printers Stratasys are suing over. If you look at the Stratasys patent, the Up! extruder – and indeed every extruder I’ve seen – is a rather different design which so far as I can tell lacks a key feature of the patent, namely the thin-walled tube running through the middle of the heater block for the filament. Stratasys’ extruder needs it because for some reason they’re feeding the filament through the heater block in a curved path, but neither Up!/PP3DP/Afinia nor any other printer does this – they feed in a straight line and use a drill hole through the heater block. (I’ve no idea how they’re managing to argue infringement – this feature is in both independent claims of their patent, so they’ve got to convince the courts Afinia’s printers have it.)
- They did not invent heated beds. Their patent is on almost any method of controlling the temperature of the environment whilst 3D printing. Nothing in the patent that I can see suggests heated beds or indeed any specific method of heating the local build environment (which they probably really ought to for the patent to be valid – am I missing something or were their patent lawyers asleep on the job?)
- They did not invent infill, the RepRap community did. No part of the patent that they claim is being infringed describes infill that even vaguely resembles the kind used by the Afinia printer. Their patent is on creating small pores in printed objects by changing how adjacent parallel rows of extruded material lay against each other. The infill they’re claiming infringes on it involves creating a rigid, thin-walled honeycomb-like structure inside the object. Quite a lot of community development went into this, and I’m pretty sure Makerbot are using it too. (Unfortunately, their claims are worded broadly enough that they may be able to argue any FDM printer that controls how air is trapped inside the printed object infringes, though it’s obvious from their wording they didn’t anticipate this technique – their claims requires the deposited strands to be “adjacent”, which arguably the honeycomb ones aren’t.)
- I’ve no idea about the seam concealment, I’ve never seen any 3D printer do that.
In short, Bre Pattis is making money from selling printers that use other people’s inventions and R&D work whilst Makerbot’s parent company sues using broad, creatively interpreted patents to make sure that no-one else can benefit from the fruits of those inventions – and yet is somehow portraying his actions as supporting innovation. This especially galls given how enthusiastically he pressured others into releasing their work in forms that allowed him to commercialise it for free.

These shows are heavily edited for brevity. Katie obviously stutters as she is recovering from something as she asks the question.
He may have corrected her, they may have just cut it out as they transition to Katie before he gets to finish. So likely they may have cut him off in audio.
