Automated sample-to-microarray apparatus and method

Patent Number: 8,965,710

AbstractAn apparatus having within or as part of a housing; a sample port; a microarray port; a lysis module; a purification module for containing a solid phase for binding of oligonucleotides; a thermocycling module for containing a polymerase chain reaction; a fragmentation module; and a microarray module for holding a microarray and a liquid in contact with the microarray. The apparatus is configured to be coupled to a device for: pumping a liquid through, in order, the lysis, purification, thermocycling, fragmentation, and microarray modules; sonicating any contents of the lysis module; thermocycling the thermocycling module to perform the polymerase chain reaction; heating the fragmentation module to fragment any oligonucleotides contained therein; circulating a fluid over the surface of the microarray; and performing one or more washing or staining steps on the microarray.

Patent Grant Time

This patent had a much slower than average grant time compared to others in this category.

Patent grant time can be influenced by many factors. Activities within the USPTO that are beyond the control of patent attornies can influence grant time, but short grant times can also indicate well-written patents and dedicated efforts to respond rapidly to USPTO office actions with strong arguments. Shorter grant times are preferable, and the scores for this section are inverse measures — higher scores are better.

Patent Claims

This patent has far fewer claims compared to others in this category.

The number of claims in a patent is correlated with its strength. Because greater claim counts increase the cost of a patent, more claims can indicate the importance an applicant assigns to a patent. Importantly, some may elect to file claims across multiple patents. A higher score in this metric indicates more claims, relative to others in this category.

Citations From Other Patents

This patent has received far fewer citations from other patents, than others in this category.

Citations from other patents are an important measure of the significance of a patent. More citations indicate that other technologies build on a patent. Higher scores in this metric are better, and indicate more citations from other patents.

Citations to Other Patents

This patent referenced many more citations to other patents, than others in this category.

A lower number of citations to other patents can be a sign of diminished patent strength. More citations indicate dependence on more other technologies. Higher scores in this category are better, and indicate fewer citations to other patents.

These are percentile ranks — they indicate the percentage of peers with lower scores.

Proximity to Basic Research



This patent has much less proximity to basic research compared to others in this category.

Proximity to basic research is measured by comparing the number of citations to non-patent literature among a cohort of patents. Because most non-patent citations are primary research papers, a higher count indicates greater proximity to basic research.
