Abstract
A fluid deposit assembly mounted on a carrier for depositing minute drops of fluid at selected locations upon a substrate, comprising a deposit element having an exposed tip of diameter of 0.3 mm or less constructed and arranged to carry and deposit drops of fluid upon the substrate, stable lateral reference surfaces or surface portions exposed for engagement by the deposit element, the surfaces or surface portions being constructed and arranged to prevent X, Y displacement of the deposit element relative to the carrier when the deposit element is urged thereagainst and design for urging the deposit element against the reference surfaces or surface portions at least at the time that the deposit element approaches a substrate to deposit a fluid drop. The reference surfaces or surface portions and the design for urging are cooperating to precisely position the deposit tip in a precisely desired position as it contacts the substrate. The deposit element is shown as the tip of an axially moveable pin. The reference surface portion is shown, among others, as a surface of revolution whose axis is disposed at a predetermined position relative to the carrier. A mobile supply in the form of a multiwell plate is moved under computer control to be a close companion of the deposit device, enabling rapid deposit action and avoidance of evaporative effects that can alter the consistency of dots in the array being formed. The device can deposit one dot on top of another from fluid in a mobile multiwell plate that moves to be close to the deposit device.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
