Why it matters

The examiner's search opinion and examination report would state the patent office's technical objections (for example, whether the "unnatural bond angle" product was found to be insufficiently disclosed, or anticipated by electrolysis prior art). These are the patent examiner's characterization, but they would be the only expert technical reading of the application on record. The USPTO office action that the parent left unanswered (abandoned 2013-09-03) is the US counterpart. Next run: open these documents (try the "Download" or Global Dossier route) and save them to research/files/.
