The experiment that answers the objection

Which objections need data

Inventive step. The technical effect of your difference over the closest prior art is far more persuasive as a measured comparison than as an assertion.

Section 3(d). A new form of a known substance needs evidence of a significant difference in properties with regard to efficacy - for a medicine, therapeutic efficacy judged strictly, and improved bioavailability alone has been held insufficient.

Section 3(e). A composition needs evidence of synergy: an effect greater than the aggregation of the components, compared against each component alone.

Sufficiency. Where a claim covers a range or a class, results at more than one point are what make it credible.

The design point

These comparisons are rarely the same as the ones an R and D team would run to answer its own question. A field trial against an untreated control shows that the product works; it does not show synergy, because nobody measured the components separately.

So the useful step is to ask, before the experiment is designed, what the patent objection will look like - and add the arm that answers it. Repeating a trial season later costs a year.

What to actually do

• Ask what objections your field always raises, then design the arm that answers each.
• Compare against each component alone, not just against a control.
• Assert the effect in the specification as filed - later data cannot rescue an unasserted effect.
• Keep the protocol and the raw data.
