The Op is showing a more professional approach. --- End quote --- Note that if there's a patent, that still doesn't mean the copy will infringe on the actual claim(s). They might be claiming a new plastic formulation or who knows what. It should be possible to design a cap for a receptacle that will be safe, IP-wise, as long as you don't overtly copy every minute detail of the existing design. Especially if you use an entirely different manufacturing process. It's absurd to let something like this interfere with shipping a product. Your approach, which will result in shipping nothing, has its risks, too. |

--- Quote from: KaneTW on August 07, 2022, 12:27:54 am ---Some googling suggests it might be https://patents.google.com/patent/EP2239605B1/en --- End quote --- If it is this patent, then manufacturing a cap is not going to infringe it, since the cap design isn’t within the scope of the invention. Then you’re in the realm of “making compatible accessories”, which you can do to your heart’s content. |

i'm not an expert.. but i would say you can't patent something that generic as a cap or lid. so if you design your own cap/lid which will be not an exact copy of the original but will do the job, then it should be fine. |

All I said was that ignoring a risk was not "common sense". |

--- Quote from: KaneTW on August 07, 2022, 12:27:54 am ---Talk with an IP lawyer. --- End quote --- Indeed. --- Quote --- That being said: Patents usually remain pending for up to 3 years. The datasheet is from 2010. They either got the patent or didn't get it, but it's unlikely it's actually still pending. --- End quote --- Not sure about timeframes (it has been a while) - but there are limits. If what is being referred to is the relevant information, then you could reasonably expect it has a definite state. --- Quote ---Some googling suggests it might be https://patents.google.com/patent/EP2239605B1/en --- End quote --- IF that is the patent, then it would seem there is no issue for the US. The legal status is showing as "Abandoned". BUT ... is that the patent of concern? |
